TECHNICAL FIELD

This application is directed to medical equipment, and in particular, toconnectors for use with medical equipment configured to determinehemodynamic parameters associated with a patient.

BACKGROUND

Some non-invasive patient monitoring devices are configured to inflate acuff to a pressure above a patient's systolic blood pressure in order toocclude arterial blood flow in the limb on which the cuff is disposed.Once above systole, the cuff can be deflated, and the systolic anddiastolic pressures of the patient can be calculated based onmeasurements made during cuff deflation.

In situations in which the patient's blood pressure and/or otherhemodynamic parameters may be monitored over extended periods, it may bedesirable to leave the cuff disposed about the patient's limb even whenthe cuff is not being used to obtain measurements. In such examples, itis common for the patient to be transferred between several differentlocations of the healthcare facility to receive care, and different cuffinflation devices or other patient monitoring system components may beconnected to the cuff at each of the different locations in order toobtain hemodynamic parameter measurements at such locations.Accordingly, there is a need for reliable and universally compatiblemeans for temporarily fluidly connecting the cuff with different patientmonitoring systems disposed at various locations throughout thehealthcare facility.

The various example embodiments of the present disclosure are directedtoward overcoming one or more of the deficiencies associated with knowncuff connection devices.

DETAILED DESCRIPTION

FIG. 1 illustrates a patient monitoring system 100, according to anexample embodiment of the present disclosure. The system 100 can beconfigured to monitor a patient, and in some embodiments, to determine ahemodynamic parameter of the patient. As used herein, the term“hemodynamic parameter” can include an indication of cardiac or vascularhealth, such as, for example, an indication of cardiac, circulatory, orvascular functionality. Specifically, a hemodynamic parameter caninclude a heart rate, a blood pressure, a vessel compliance, asaturation of hemoglobin with oxygen in arterial blood (i.e., an SpO₂measurement), an aortic index, an augmentation index, reflected waveratio, or an indication of treatment. Blood pressure can includesystolic, suprasystolic, diastolic, or mean atrial pressure. It isunderstood that such blood pressures may be represented as a systolicblood pressure over a diastolic blood pressure, and that a mean oraverage blood pressure may be represented as an average systolic bloodpressure over an average diastolic blood pressure. Moreover, anindication of treatment can include a parameter reflecting the affect ofa drug treatment, or one or more treatments of a disease state.

The system 100 can include a cuff 12 configured to at least to partiallyocclude the movement of blood through a blood vessel 10 of a patient 14such as an artery, vein, or the like. In some embodiments, the cuff 12can be configured to completely occlude an artery of patient 14. In anyof the embodiments described herein, however, the system 100 may betuned and/or otherwise configured to determine one or more hemodynamicparameters of the patient 14, such as a blood pressure of the patient14, without completely occluding the blood vessel 10. In suchembodiments, the system 100, and/or components thereof, may determinethe blood pressure of the patient 14 before the cuff 12 is inflated to apressure associated with complete occlusion of the blood vessel 10and/or before a systolic blood pressure of the patient 14 is reached.Although shown in FIG. 1 surrounding an arm 22 of the patient 14, thecuff 12 may be adapted for placement on (i.e., around) any suitable bodypart of patient 14, including, for example, a wrist, a finger, an upperthigh, an ankle, or any other like limb or body part. In addition, oneor more cuffs 12 could be placed at different locations about thepatient 14 for use with the system 100.

The cuff 12 can include one or more bladders or other like inflatabledevices, and the pressure or volume within the cuff 12 may be controlledby any known inflation device (not shown). Such inflation devices caninclude a pump or similar device configured to controllably inflateand/or deflate the inflatable device of the cuff 12. For example, suchinflation devices could supply the cuff 12 with a fluid to increase thepressure or volume of the cuff 12. In other embodiments, one or moreinflation devices could include mechanical, electrical, or chemicaldevices configured to occlusion of the blood vessel 10 via the cuff 12.Such inflation devices may comprise a component of the system 100 andmay be included within and/or operably connected to, for example, acontroller 20 of the system 100. In some embodiments, such inflationdevices can inflate the cuff 12 to or towards a target inflationpressure, and may be configured to generally maintain the cuff 12 at anydesired inflation pressure for a desired period of time. In someembodiments, the target inflation pressure may be less than or equal tothe systolic pressure of the patient 14. Alternatively, in furtherembodiments the target pressure may be greater than the systolicpressure of the patient 14. In example embodiments, the system 100 maydetermine the blood pressure of the patient 14 without inflating thecuff to the systolic pressure. Accordingly, even in embodiments in whichalgorithms, controllers, and/or other components of the system 100employ a target inflation pressure that is equal to or greater than thesystolic pressure, the system 100 may discontinue inflation of the cuff12 at an inflation pressure less than such a target inflation pressure.Although such embodiments may use a target inflation pressure equal toor greater than the systolic pressure, discontinuing inflation of thecuff 100 at a pressure below such a target inflation pressure may avoidpatient discomfort during blood pressure determination.

The system 100 can further include a sensor 18 configured to receive asignal associated with the patient 14. In some embodiments, the sensor18 can be configured to receive a signal associated with an at leastpartially occluded vessel 10 of the patient 14. Such an input signal canarise from blood movement through the partially occluded vessel 10 orfrom a signal associated with an occluded blood vessel 10. The sensor 18could sample multiple times at various intervals. In yet otherembodiments, the sensor 18 could provide an indication of blood vesselmovement, such as, for example, oscillations arising from vascularexpansion or contraction. For example, the sensor 18 could be configuredto detect a pressure or volume of cuff 12 that may vary periodicallywith the cyclic expansion and contraction of the blood vessel 10 of thepatient 14. In particular, the sensor 18 could determine a bloodpressure, various pulses of blood through the blood vessel 10, an oxygensaturation of the blood, or any other hemodynamic parameter associatedwith the patient 14 using an auscultation, oscillometric, or other knownmeasurement method.

In some embodiments, the sensor 18 could detect a volume or a pressureassociated with cuff 12. For example, the sensor 18 could include apressure transducer or other like pressure sensor, and may be locatedwithin, on, or about the cuff 12 or other parts of the system 100. Insuch embodiments, the sensor 18 may be configured to sense, measure,detect, monitor, calculate, and/or otherwise “determine” one or moreblood pressure pulses associated with the patient 14. Each bloodpressure “pulse” may be indicative of, for example, the movement ofblood through the blood vessel 10 by the heart of the patient 14 duringsystole, and the number of such pulses per minute may comprise the heartrate of the patient 14.

The controller 20 may comprise and/or otherwise include one or moreprocessors, microprocessors, programmable logic controllers, and/orother like components configured to control one or more operations ofthe cuff 12, the cuff inflation devices, the sensor 18, and/or othercomponents of the system 100 connected to the controller 20. Forexample, the controller 20 can control inflation and/or deflation of thecuff 12 via control of the inflation devices described above.

In some embodiments, the controller 20 can sense, measure, detect,monitor, calculate, and/or otherwise determine a blood pressure of thepatient 14 based on one or more of the hemodynamic parameters determinedby the sensor 18. This determination may be based on one or more outputsignals received from sensor 18, as described above. In someembodiments, the controller 20 may also include one or more sensors,similar to the sensor 18, configured to sense, measure, detect, monitor,calculate, and/or otherwise determine one or more blood pressure pulsesassociated with the patient 14, a pressure or volume of cuff 12, and/orany of the other hemodynamic parameters described herein. The controller20 may also control inflation of cuff 12 (via one or more of theinflation devices described herein) toward a target inflation pressure,or generally maintaining inflation of cuff 12 at about the targetpressure. Such a target inflation pressure may be a pressure that isgreater than, equal to, or less than, for example, a systolic pressureof the patient 14 and/or the mean arterial pressure of the patient. Forexample, as noted above, the system 100 may determine the blood pressureof the patient 14 without inflating the cuff to the systolic pressure.Accordingly, even in embodiments in which the controller 20 employs atarget inflation pressure that is equal to or greater than the systolicpressure for purposes of cuff inflation, algorithms of the controller 20may discontinue inflation of the cuff 12 at an inflation pressure lessthan such a target inflation pressure. Despite the use of such exampletarget inflation pressures, the controller 20 may determine the bloodpressure of the patient 14 without completely occluding the blood vessel10.

Although not shown in FIG. 1 , in additional example embodiments, thesystem 100 can optionally include a signal analysis module. For example,the signal analysis module may be configured to analyze one or moresignals received from the sensor 18 using one or more processors of thecontroller 20. For example, the signal analysis module can include oneor more filters configured to filter a signal associated with the sensor18 or the controller 20. Such filters can include band-pass, high-pass,or low-pass filters.

As illustrated in FIG. 1 , the system 100 may also include a memory 24operably connected to the controller 20. The memory 24 may include, forexample, a hard drive, a thumb drive, and/or any other like fixed orremovable storage device known in the art. Such memory 24 may compriserandom access memory, read-only memory, transient memory, non-transientmemory, and/or any other like information storage means. In suchembodiments, the memory 24 may be configured to store signals, data,values, curves, thresholds, and/or any other like information receivedfrom the sensor 18. The memory 24 may also be configured to storesignals, data, values, thresholds, curves, and/or any other likeinformation determined by the controller 20 during the variousoperations described herein. For example, the memory 24 may beconfigured to store one or more pressure pulses, pulse profiles, pulseheights, pulse curves, target inflation pressures, pressure thresholds,and/or other like information. Additionally, the memory 24 may beconfigured to store one or more algorithms, protocols and/or other likeprograms associated with calculating and/or otherwise determining theblood pressure of the patient 14. Additionally, the memory 24 may beconfigured to store one or more sets of values corresponding to pointson one or more pulse curves. Such information may be recalled and/orotherwise utilized by the controller 20 during one or more bloodpressure determination methods described herein.

The system 100 can further include a user interface 16 configured toprovide communication to the patient 14 or one or more operators. Forexample, the user interface 16 could include a display configured tocommunicate and/or otherwise output one or more hemodynamic parameters.The user interface 16 may further include one or more speakers or otherlike audio devices configured to communicate and/or otherwise outputinformation to the patient 14 and/or a user operator of the system 100.In further embodiments, the system 100 may include one or moretransmitters, network devices, routers, Bluetooth® devices, WiFi®devices, radio devices, and/or other like communication device 26configured to transmit data to a remote location and/or to a remotedevice. In such embodiments, the communication device 26 may enable thetransmission of information to or from the controller 20. It isunderstood, that such communication devices 26 may facilitate thetransmission of such information via wired or wireless means. Forexample, in any of the embodiments described herein, one or morecomponents of the system 100, such as the controller 20, may be disposedremote from a remainder of the components of the system 100. In suchembodiments, for example, the controller 20 may be disposed in adifferent location of a healthcare facility than the cuff 12, userinterface 16, or other components of the system 100. Alternatively, infurther embodiments, the controller 20 may be in a first healthcarefacility and a remainder of the components of the system 100 may belocated in a second healthcare facility different from the firstfacility. In such embodiments, the various components of the system 100may be in communication and/or otherwise operably connected via thecommunication devices 26 described herein.

In addition to the components outlined above, the system 100 may includevarious other component, such as, for example, a power source and/or auser input device. One or more components described herein may becombined or may be separate independent components of the system.Moreover, the various components of the system 100 could be integratedinto a single processing unit or may operate as separate processors. Inoperation, one or more processors can be configured to operate inconjunction with one or more software programs to provide thefunctionality of the system 100. For example, one or more of thecomponents described above with respect to the system 100 may includeone or more hardware components and/or one or more software componentsconfigured to control operation of such components and/or of the system100.

The system 100 of the present disclosure may also include one or morecomponents configured to fluidly connect the cuff 12 with the controller20, and in particular, with one or more inflation devices operablyconnected to the controller 20. For example, the controller 20 mayinclude first and second connectors 28 a, 28 b fluidly coupled to one ormore of the inflation devices described herein. The first and secondconnectors 28 a, 28 b may comprise male barbs or other like connectorsdefining a respective lumen through which pressurized air or otherfluids may pass from the inflation devices to tubing 30 fluidlyconnected to the one or more connectors 28 a, 28 b. For example, thetubing 30 may comprise dual-lumen tubing having first and secondconnected conduit sections 32 a, 32 b sharing a substantially smoothintegrated outer surface. In such embodiments, an orifice 34 a of thefirst section 32 a at a proximal end 36 of the tubing 30 may beconfigured to form a substantially fluid-tight connection with the firstconnector 28 a. Similarly, an orifice 34 b of the second section 32 b atthe proximal end 36 of the tubing 30 may be configured to form asubstantially fluid-tight connection with the second connector 28 b.Alternatively, in other embodiments, the tubing 30 may comprisesingle-lumen tubing, and a first section of the single-lumen tubing maybe configured to form a substantially fluid-tight connection with thefirst connector 28 a while a second section of the single-lumen tubing30 may be configured to form a substantially fluid-tight connection withthe second connector 28 b. For ease of discussion, the tubing 30 shallbe described herein as dual-lumen tubing unless otherwise noted. In anyof the embodiments described herein, the tubing 30 may comprise aflexible, durable, medically approved material such as a thermoplasticelastomer, and the tubing 30 may be made from processes includingextrusion molding.

The first section 32 a of the tubing 30 may also include an orifice 38 aat a distal end 40 of the tubing 30, and the second section 32 b mayinclude a similar orifice 38 b at the distal end 40. The orifices 38 a,38 b may be configured to form a substantially fluid-tight connectionwith a fitting 42 of the present disclosure. As will be described ingreater detail below, the fitting 42 may have various differentconfigurations, and any of the fittings described herein may be employedby the system 100 in order to assist in fluidly connecting the cuff 12with the controller 20 and/or other components of the system 100. Insome examples, the fitting 42 may comprise a dual-shaft connector (e.g.,a connector having two shafts configured to mate with dual lumen tubing30), while in other examples, the fitting 42 may comprise a single-shaftconnector. For ease of discussion, the fitting 42 shall be describedherein as dual-shaft connector unless otherwise noted.

The fitting 42 may include, for example, first and second shafts 44 a,44 b, and a proximal end portion of the first shaft 44 a may beconfigured to form a substantially fluid-tight connection with the firstsection 32 a of the tubing 30, while a proximal end portion of thesecond shaft 44 b may be configured to form a substantially fluid-tightconnection with the second section 32 b of the tubing 30. In particular,a barb or other like connector may be formed at proximal end portions ofthe first and second shafts 44 a, 44 b, and such barbs may be insertedinto the respective orifices 38 a, 38 b of the tubing 30 to form such asubstantially fluid-tight connection between the fitting 42 and thetubing 30. In some examples, the barbs formed at each of the proximalend portions may be substantially similar to and/or the same as thefirst and second connectors 28 a, 28 b described above. The first andsecond shafts 44 a, 44 b may define respective lumens passingtherethrough and configured to fluidly connect, the tubing 30 with, forexample, the cuff 12 via one or more adapters 50 of the cuff 12. Forexample, as will be described in greater detail below, the fitting 42may be removably attachable to a corresponding adapter 50 of the cuff12, and a substantially fluid tight seal may be formed between thefitting 42 and such an adapter 50 when the fitting 50 is removablyattached to the adapter. The fitting 42 may include one or more grips 46a, 46 b connected to a body 48 of the fitting 42, and such grips 46 a,46 b may be configured to assist in removably attaching the fitting 42to the adapter 50. It is understood that when the fitting 42 isremovably attached to the blood pressure cuff adapter 50, the fitting 42may be fluidly connected to the adapter 50 and/or to the cuff 12. Thus,when the fitting 42 is removably attached to the blood pressure cuffadapter 50, the fitting 42 may be configured to direct pressurized airor other fluids to the cuff 12, via the adapter 50, to assist in atleast partially inflating the cuff 12.

FIG. 2 illustrates the example fitting 42 and the example blood pressurecuff adapter 50 of FIG. 1 in greater detail. As shown in FIG. 2 , in anexample system 100 or other environment, the grips 46 a, 46 b of thefitting 42 may extend from the body 48, and at least part of the fitting42 coupling the grips 46 a, 46 b to the body 48 may be relativelyflexible. For example, the body 48 may be made from a firstsubstantially rigid material, and such a material may include, forexample, one or more metals, alloys, plastics, polymers, or othermaterials. Such materials may include, for example, polyethylene,polypropylene, and/or other medically approved materials. In suchexamples, the grips 46 a, 46 b may be connected to the body 48 viarespective first and second stands 66 a, 66 b extending from the body48. In some examples, the stands 66 a, 66 b may be made from any of thematerials described above with respect to the body 48, while in otherexamples, one or more of the stands 66 a, 66 b may be made from amaterial that is relatively more flexible than the material used to formthe body 48. In any such examples, the shape, size, materials, and/orother configuration of the stands 66 a, 66 b may provide for movement ofthe respective grips 46 a, 46 b relative to the body 48 when force isapplied to the respective grips 46 a, 46 b by a user of the fitting 42.Such movement may enable the fitting 42 to be removably attached to theblood pressure cuff adapter 50, and may also enable the fitting 42 to bedetached from the adapter 50. For example, the fitting 42 may includeone or more arms 62 a, 62 b extending from a respective grip 46 a, 46 band/or from a respective stand 66 a, 66 b. In such examples, a first arm62 a may extend substantially perpendicularly from the first grip 46 a,and a second arm 62 b may extend substantially perpendicularly from thesecond grip 46 b. The first and second arms 62 a, 62 b may includerespective first and second shelves 64 a, 64 b extending substantiallyparallel to the respective grips 46 a, 46 b. As can be seen from FIG. 2, the first and second shelves 64 a, 64 b may also extend substantiallyperpendicularly from the respective arms 62 a, 62 b. In particular, suchfirst and second shelves 64 a, 64 b may include one or more surfaces(e.g., a top surface, a bottom surface opposite the top surface, a sidesurface, etc.), extending substantially perpendicularly from therespective arms 62 a, 62 b, and such surfaces may be configured to matewith a corresponding surface of the adapter 50 in order to removablyattach the fitting 42 to the adapter. The fitting 42 may also includeone or more extensions, passages, and/or other like channels 68extending from the body 48. In some examples, such as the example shownin FIG. 2 , the channel 68 may extend substantially along a longitudinalaxis Z of the fitting 42, and the longitudinal axis Z may extendsubstantially centrally through the channel 68. As will be described infurther detail below, in some examples, the channel 68 may form at leastpart of a central fluid passage extending through at least part of thefitting 42. The channel 68 may also form an opening 70 configured topermit the passage of air or other fluids into the cuff 12 via thefitting 42 (e.g., via the central passage of the fitting 42), and/or tootherwise fluidly connect the fitting 42 with the cuff 12 when thefitting 42 is removably attached to the adapter 50.

As shown in FIG. 2 , in some examples the adapter 50 may include asubstantially rigid body 52 that is at least partly connected to thecuff 12. For example, the body 52 may include a distal portion extendingoutwardly from a top or outer surface 54 of the cuff 12. The body 52 mayalso include a proximal portion embedded within the cuff 12 and/orextending inwardly from the outer surface 54. In some examples, theproximal portion of the body 52 may extend at least partly along and/ormay be connected to an inner surface of the cuff 12 disposed oppositethe outer surface 54. Alternatively, in any of the example embodimentsdescribed herein the adapter 50 may be fluidly connected to the cuff 12via one or more lengths of tubing 30 and/or other components of thesystem 100. For instance, in such examples a length of tubing 30 may befluidly connected to an internal bladder and/or other inflatable portionof the cuff 12, and the length of tubing 30 may extend outwardly fromthe bladder and/or other inflatable portion by any desired distance(e.g., one foot, 18 inches, two feet, etc.). In such examples, theadapter 50 may be fluidly, removably, permanently, and/or otherwiseconnected to an end of the tubing 30 opposite the cuff 12, and theadapter 50 may be configured to facilitate a removable and/or releasableconnection with the fitting 42 at a location spaced from the cuff 12.

With continued reference to FIG. 2 , the body 54 may be made from any ofthe materials described above with respect to, for example, the fitting42. In some examples, the adapter 50 may be made from more than one suchmaterial. For example, one or more components or other parts of thedistal portion may be made from a first material, and one or morecomponents or other parts of the proximal portion may be made from asecond material different from the first material. In such examples, theuse of such first and second materials may result in the variouscomponents or other parts of the body 52 having different rigidities,durabilities, sealing characteristics, and/or other properties. Forexample, a ridge 58 or other part of the body 52 mating with the shelves64 a, 64 b of the fitting 42 may be made from a first relatively rigidmaterial to assist in securely removably attaching the fitting 42 to theadapter 50. In such examples, at least part of a ring 56 (e.g., a topsurface and/or an inner wall of the ring 56) or other part of the body52 forming a substantially fluid-tight seal with a corresponding surfaceof the fitting 42 may be made from a second relatively flexible materialdifferent from the first material to assist in forming such asubstantially fluid-tight seal.

In any of the examples described herein, the body 52 of the adapter 50may also include a central opening 60 at least partially formed by aninner wall 59 of the body 52. For example, the inner wall 59 maycomprise a substantially cylindrical inner wall, and the inner wall 59may define a central fluid passage of the adapter 50 configured toaccept air or other fluids delivered to the cuff 12 via the fitting 42.In such examples, the inner wall 59 may have any shape, size, diameter,and/or other configuration such that the inner wall 59 may accept atleast part of the channel 68 therein. For example, a substantiallycylindrical inner wall 59 may define a substantially circular opening 60through which at least part of the channel 68 may pass when the fitting42 is removably attached to the adapter 50. In this way, at least partof the channel 68 may extend into and/or may otherwise be disposedwithin the inner wall 59, via the opening, when the fitting 42 isremovably attached to the adapter 50. In any of the examples describedherein, the body 52 may further include a longitudinal axis X, and insuch examples, the longitudinal axis X may extend substantiallycentrally through the opening 60 and/or through the substantiallycylindrical inner wall 59. As will be described in greater detail below,in any of the examples described herein the ring 56 formed by the body52 may comprise a substantially annular ring, flange, and/or otherportion of the adapter 50, and the ring 56 may include a top surfacedisposed opposite the proximal portion of the body 52. In such examples,the ridge 58 may be disposed opposite the top surface of the ring 56 an,in some examples, the ridge 58 may comprise at least part of a bottomsurface of the ring 56. At least part of the ridge 58 and/or at leastanother part of the bottom surface of the ring 56 may be configured tomate with the shelves 64 a, 64 b of the fitting 42 to assist inretaining the fitting 42 and/or otherwise removably attaching thefitting 42 to the adapter 50. In some examples, at least part of theridge 58 and/or at least another part of the bottom surface of the ring56 may extend substantially perpendicular to the longitudinal axis X ofthe body 52.

As shown in FIG. 3 , an example system 300 or other environment mayinclude a fitting 302 and/or a blood pressure cuff adapter 304, and insuch systems, the example fitting 302 may be removably attachable tosuch an adapter 304. The fitting 302 and/or the adapter 304 may includevarious structures and/or other components configured to assist informing such a removable connection, and one or more such components mayalso assist in forming a substantially fluid-tight seal between thefitting 302 and the adapter 304 when the fitting 302 is removablyattached to the adapter 304. In example embodiments, any of thestructures, functions, and/or other aspects of the fitting 42 describedherein with respect to FIGS. 1 and 2 may be included in the fitting 302and/or in any of the other example fittings described herein. Likewise,any of the structures, functions, and/or other aspects of the adapter 50described herein with respect to FIGS. 1 and 2 may be included in theadapter 304 and/or in any of the other example blood pressure cuffadapters described herein. Further, one or more of the structures,functions, and/or features of the fitting 302, and/or of the adapter304, may be incorporated into any of the fittings or adapters of thepresent disclosure.

In the example system 300, the fitting 302 may include a substantiallyrigid body 306, and one or more arms 308 a, 308 b extending from thebody 306. The first and second arms 308 a, 308 b may also includerespective shelves 310 a, 310 b formed at respective distal ends of thearms 308 a, 308 b. At least one of the arms 308 a, 308 b and/or at leastone of the shelves 310 a, 310 b may be substantially similar to and/orthe same as the arms 62 a, 62 b and/or the shelves 64 a, 64 b describedabove. For example, the arm 308 b may be movably connected to the body306 via at least one stand 312 extending from the body 306. As can beseen from FIG. 3 , the first and second shelves 310 a, 310 b may extendsubstantially perpendicularly from the respective arms 308 a, 308 b. Inparticular, such first and second shelves 310 a, 310 b may include oneor more surfaces (e.g., a top surface, a bottom surface opposite the topsurface, a side surface, etc.), extending substantially perpendicularlyfrom the respective arms 308 a, 308 b, and such surfaces may beconfigured to mate with a corresponding surface of the adapter 304 inorder to removably attach the fitting 302 to the adapter 304.

At least one of the body 306, stands 312, arms 308 a, 308 b, shelves 310a, 310 b, and/or other components of the fitting 302 may be made fromany of the materials described above with respect to the body 48. In anysuch examples, the shape, size, materials, and/or other configuration ofthe stand 312 may provide for movement of the corresponding shelf 310 brelative to the body 306 when force is applied to a grip 314 associatedwith the stand 312. Such movement may enable the fitting 302 to beremovably attached to the blood pressure cuff adapter 304, and may alsoenable the fitting 302 to be detached from the adapter 304. For example,in the system 300 the arm 308 a and/or the shelf 310 a may remainsubstantially stationary relative to the body 306 when the fitting 302is removably attached to and/or detached from the blood pressure cuffadapter 304.

The fitting 302 may also include one or more extensions, passages,and/or other like channels 316 extending from the body 306. In someexamples, the channel 316 may extend substantially along thelongitudinal axis Z (FIG. 2 ) of the fitting 302, and the longitudinalaxis Z may extend substantially centrally through the channel 316. Thechannel 316 may form an opening 318 configured to permit the passage ofair or other fluids into the cuff 12 via the fitting 302, and/or tootherwise fluidly connect the fitting 302 with the cuff 12, when thefitting 302 is removably attached to the adapter 304. The fitting 302may further include a central fluid passage 319 extending at leastpartially through the body 306. For example, the channel 316 may form atleast part of the central fluid passage 319, and the longitudinal axis Z(FIG. 2 ) may extend substantially centrally through at least part ofthe central passage 319. In such examples, the opening 318 of thechannel 316 may comprise an opening of the central passage 319.

As noted above with respect to the adapter 50 of FIG. 2 , the adapter304 may include a substantially rigid body 320 that is at least partlyconnected to the cuff 12. For example, the body 320 may include a distalportion 321 extending outwardly from the outer surface 54 of the cuff12. The body 320 may also include a proximal portion 336 embedded withinthe cuff 12 and/or extending inwardly from the outer surface 54. In someexamples, a top surface 340 of the proximal portion 336 may extend atleast partly along and/or may be connected to an inner surface of thecuff 12 disposed opposite the outer surface 54. The body 320 of theadapter 304 may be made from any of the materials described above withrespect to, for example, the fitting 42. In some examples, the adapter304 may be made from more than one such material. For example, one ormore components or other parts of the distal portion 321 may be madefrom a first material, and one or more components or other parts of theproximal portion 336 may be made from a second material different fromthe first material. As noted above with respect to the adapter 50 ofFIG. 2 , in such examples, the use of such first and second materialsmay result in the various components or other parts of the body 320having different rigidities, durabilities, sealing characteristics,and/or other properties.

The distal portion 321 of the adapter 304 may include an annular ring322 having a top surface 326 and a ridge 324 disposed opposite the topsurface 326. The ridge 324 may comprise at least part of a bottomsurface of the ring 322. In such examples, at least part of the ridge324 and/or at least another part of the bottom surface of the ring 322may be configured to mate with the shelves 310 a, 310 b of the fitting302 to assist in retaining the fitting 302 and/or otherwise removablyattaching the fitting 302 to the adapter 304. In some examples, at leastpart of the ridge 324 and/or at least another part of the bottom surfaceof the ring 322 may extend substantially perpendicular to a longitudinalaxis X of the body 320. Additionally, the adapter 304 may include asubstantially cylindrical sidewall 338 extending from the ridge 324 tothe top surface 340 of the proximal portion 336. Such a sidewall 338 mayspace the ridge 324 from the top surface 340 such that the shelves 310a, 310 b of the fitting 302 may have room to mate with the ridge 324beneath the ring 322.

The top surface 326 of the ring 322 may be substantially convex,substantially concave, substantially curved, substantially tapered,and/or any other configuration in order to assist in removably attachingthe fitting 302 to the adapter 304. In some examples, the top surface326 of the ring 322 may comprise a convex surface extending radiallyaway from the longitudinal axis X of the body 320 from a distal end(e.g., a radially innermost end) 330 of the top surface 326 to aproximal end (e.g., a radially outermost end) 332 of the top surface326. In such examples, the curved top surface 326 may comprise a cammingsurface along which at least part of the arm 308 b and/or othercomponents of the fitting 302 may slide as the fitting 302 is removablyattached to the adapter 304.

The system 300 may also include one or more O-rings, gaskets, and/orother seals 328 configured to form a substantially fluid-tight sealbetween the fitting 302 and the adapter 304 when the fitting 302 isremovably attached to the adapter 304. For example, in any of theexample embodiments described herein, at least one seal 328 may beattached to, adhered to, embedded substantially within, formedintegrally with, and/or otherwise connected to either an outer surface334 of the fitting 302 or to the top surface 326 of the ring 326 tofacilitate forming such a fluid-tight seal. In the example system 300 ofFIG. 3 , at least part (e.g., a base) of the seal 328 may be disposedwithin an annular groove 346 formed by the top surface 326 of the ring322. In such examples, the seal 328 may engage the outer surface 334 ofthe fitting 302 to form a substantially fluid-tight seal with thefitting 302 when the fitting 302 is removably attached to the adapter304. Alternatively, in any of the example embodiments described herein,the seal 328 may be attached to, adhered to, embedded substantiallywithin, formed integrally with, and/or otherwise connected to the outersurface 334 of the fitting 302, and may be configured to engage the topsurface 326 to form such a substantially fluid-tight seal. In exampleembodiments in which the seal 328 is formed integrally with the adapter304, the seal 328 may comprise, for example, a relatively flexibleand/or a relatively thin portion of the ring 322. Alternatively, inexample embodiments in which the seal 328 is formed integrally with thefitting 302, the seal 328 may comprise a relatively flexible and/or arelatively thin portion of the outer surface 334. In still furtherexample embodiments, the seal 328 may be separable from (e.g., removablyattached to) either the fitting 302 or the adapter 304. In suchexamples, the seal 328 may be press fit within, dove-tailed within,and/or otherwise at least partly disposed within a groove 346, channel,and/or other structure formed by either the fitting 302 or the adapter304 to facilitate such removable attachment thereto.

Further, the body 320 of the adapter 304 may also include a centralopening (as shown more clearly in FIG. 2 ) at least partially formed byan inner wall 344 of the body 320. For example, the inner wall 344 ofthe body 320 may comprise a substantially cylindrical inner wall, andthe inner wall 344 may define a central fluid passage of the adapter 304configured to accept air or other fluids delivered to the cuff 12 viathe fitting 302. In such examples, the inner wall 344 may have anyshape, size, diameter, and/or other configuration such that the innerwall 344 may accept at least part of the channel 316 therein. Forexample, at least part of the channel 316 may pass through the centralopening of the inner wall 344, proximate the distal end 330 of the topsurface 326, when the fitting 302 is removably attached to the adapter304. The inner wall 344 may extend from the distal end 330 of the topsurface 326 to a bottom surface 342 of the body 320 formed by theproximal portion 326. In any of the examples described herein, the body320 may further include a longitudinal axis X, and in such examples, thelongitudinal axis X may extend substantially centrally through thecentral fluid passage of the adapter 304 formed by the substantiallycylindrical inner wall 344.

As shown in FIGS. 4 and 4 a, an example system 400 or other environmentof the present disclosure may include a fitting 402 that issubstantially similar to the fitting 302, and/or may include a bloodpressure cuff adapter 404 that is substantially similar to the bloodpressure cuff adapter 304. In such systems 400, the example fitting 402may be removably attachable to such an adapter 404, and unlike thefitting 302 illustrated in FIG. 3 , the fitting 402 may include a pairof stands 412 a, 412 b movably connecting respective arms 408 a, 408 bof the fitting 402 to a body 406 of the fitting 402. The fitting 402and/or the adapter 404 may include various structures and/or othercomponents configured to assist in forming a removable connectiontherebetween, and one or more such components may also assist in forminga substantially fluid-tight seal between the fitting 402 and the adapter404 when the fitting 402 is removably attached to the adapter 404. Inexample embodiments, any of the structures, functions, and/or otheraspects of the various fittings described herein may be included in thefitting 402. Likewise, any of the structures, functions, and/or otheraspects of the various adapters described herein may be included in theadapter 404. Further, one or more of the structures, functions, and/orfeatures of the fitting 402, and/or of the adapter 404, may beincorporated into any of the fittings or adapters of the presentdisclosure.

In the example system 400, various components of the fitting 402 may besubstantially similar to corresponding components of the fitting 302,and various components of the adapter 404 may be substantially similarto corresponding components of the adapter 304. For example, the fitting402 may include a substantially rigid body 406, and one or more arms 408a, 408 b extending from the body 406. The first and second arms 408 a,408 b may also include respective shelves 410 a, 410 b formed atrespective distal ends of the arms 408 a, 408 b. In such examples, thearm 408 a may be movably connected to the body 406 via a stand 412 aextending from the body 406, and the arm 408 b may be movably connectedto the body 406 via a stand 412 b extending from the body 406. As can beseen from FIG. 4 , the first and second shelves 410 a, 410 b may extendsubstantially perpendicularly from the respective arms 408 a, 408 b. Inparticular, such first and second shelves 410 a, 410 b may include oneor more surfaces (e.g., a top surface, a bottom surface opposite the topsurface, a side surface, etc.), extending substantially perpendicularlyfrom the respective arms 408 a, 408 b, and such surfaces may beconfigured to mate with a corresponding surface of the adapter 404 inorder to removably attach the fitting 402 to the adapter 404.

At least one of the body 406, stands 412 a, 412 b, arms 408 a, 408 b,shelves 410 a, 410 b, and/or other components of the fitting 402 may bemade from any of the materials described above with respect to the body48. In any such examples, the shape, size, materials, and/or otherconfiguration of the stands 412 a, 412 b may provide for movement of thecorresponding arms 408 a, 408 b and/or shelves 410 a, 410 b relative tothe body 406 when force is applied to respective grips 414 a, 414 bassociated with the stands 412 a, 412 b. Such movement may enable thefitting 402 to be removably attached to the blood pressure cuff adapter404, and may also enable the fitting 402 to be detached from the adapter404.

The fitting 402 may also include one or more extensions, passages,and/or other like channels 416 extending from the body 406. In someexamples, the channel 416 may extend substantially along thelongitudinal axis Z (FIG. 2 ) of the fitting 402, and the longitudinalaxis Z may extend substantially centrally through the channel 416. Thechannel 416 may form an opening 418 configured to permit the passage ofair or other fluids into the cuff 12 via the fitting 402, and/or tootherwise fluidly connect the fitting 402 with the cuff 12, when thefitting 402 is removably attached to the adapter 404. The fitting 402may further include a central fluid passage 419 extending at leastpartially through the body 406. For example, the channel 416 may form atleast part of the central fluid passage 419 of the fitting 402, and thelongitudinal axis Z (FIG. 2 ) may extend substantially centrally throughat least part of the central passage 419. In such examples, the opening418 of the channel 416 may comprise an opening of the central passage419.

As noted above with respect to the adapter 50 of FIG. 2 , the adapter404 may include a substantially rigid body 420 that is at least partlyconnected to the cuff 12. For example, the body 420 may include a distalportion 421 extending outwardly from the outer surface 54 of the cuff12. The body 420 may also include a proximal portion 436 embedded withinthe cuff 12 and/or extending inwardly from the outer surface 54. In someexamples, a top surface of the proximal portion 436 may extend at leastpartly along and/or may be connected to an inner surface of the cuff 12disposed opposite the outer surface 54. The body 420 of the adapter 404may be made from any of the materials described above with respect to,for example, the fitting 42. In some examples, the adapter 404 may bemade from more than one such material. For example, one or morecomponents or other parts of the distal portion 421 may be made from afirst material, and one or more components or other parts of theproximal portion 436 may be made from a second material different fromthe first material. As noted above with respect to the adapter 50 ofFIG. 2 , in such examples, the use of such first and second materialsmay result in the various components or other parts of the body 420having different rigidities, durabilities, sealing characteristics,and/or other properties.

The distal portion 421 of the adapter 404 may include an annular ring422 having a top surface 426 and a ridge 424 disposed opposite the topsurface 426. The ridge 424 may comprise at least part of a bottomsurface of the ring 422. In such examples, at least part of the ridge424 and/or at least another part of the bottom surface of the ring 422may be configured to mate with the shelves 410 a, 410 b of the fitting402 to assist in retaining the fitting 402 and/or otherwise removablyattaching the fitting 402 to the adapter 404. In some examples, at leastpart of the ridge 424 and/or at least another part of the bottom surfaceof the ring 422 may extend substantially perpendicular to a longitudinalaxis X of the body 420. Additionally, the adapter 404 may include asubstantially cylindrical sidewall extending from the ridge 424 to thetop surface of the proximal portion 436. Such a sidewall may space theridge 424 from the top surface of the proximal portion 436 such that theshelves 410 a, 410 b of the fitting 402 may have room to mate with theridge 424 beneath the ring 422.

The top surface 426 of the ring 422 may be substantially convex,substantially concave, substantially curved, substantially tapered,and/or any other configuration in order to assist in removably attachingthe fitting 402 to the adapter 404. In some examples, the top surface426 of the ring 422 may comprise a convex surface extending radiallyaway from the longitudinal axis X of the body 420 from a distal end 430of the top surface 426 to a proximal end 432 of the top surface 426. Insuch examples, the curved top surface 426 may comprise a camming surfacealong which at least part of the arms 408 a, 408 b and/or othercomponents of the fitting 402 may slide as the fitting 402 is removablyattached to the adapter 404.

The system 400 may also include one or more O-rings, gaskets, and/orother seals configured to form a substantially fluid-tight seal betweenthe fitting 402 and the adapter 404 when the fitting 402 is removablyattached to the adapter 404. For example, at least one seal 428 (FIG. 4) may be attached to, adhered to, embedded substantially within, and/orotherwise connected to either an outer surface 434 of the fitting 402 orto the top surface 426 of the ring 422 to facilitate forming such afluid-tight seal. In the example system 400 of FIG. 4 , at least part(e.g., a base) of the seal 428 may be disposed within an annular grooveformed by the top surface 426 of the ring 422. In such examples, theseal 428 may engage the outer surface 434 of the fitting 402 proximate aperimeter and/or outer wall of the channel 416 to form a substantiallyfluid-tight seal with the fitting 402 when the fitting 402 is removablyattached to the adapter 404. Alternatively, the seal 428 may be attachedto, adhered to, embedded substantially within, and/or otherwiseconnected to the outer surface 434 of the fitting 402, and may beconfigured to engage the top surface 426 of the adapter 404 to form sucha substantially fluid-tight seal.

As shown in the partial cross-section of FIG. 4 a , in an alternativeexample a first seal 428 a may be attached to, adhered to, embeddedsubstantially within, formed integrally with, and/or otherwise connectedto the outer surface 434 of the fitting 402, and a second seal 428 b maybe attached to, adhered to, embedded substantially within, formedintegrally with, and/or otherwise connected to the top surface 426 ofthe ring 422. In such embodiments, the first seal 428 a may beconfigured to engage contact, interlock, and/or otherwise mate with thesecond seal 428 b when the fitting 402 is removably attached to theadapter 402, thereby forming such a fluid-tight seal. In the examplesystem 400 of FIG. 4 a , at least part (e.g., a base 438) of the firstseal 428 a may be disposed within an annular groove formed by the outersurface 434 of the fitting 402, and at least part (e.g., a base 440) ofthe second seal 428 b may be disposed within a similar annular grooveformed by the top surface 426 of the ring 422. In such examples, thefirst seal 428 a may include a sealing surface 442 disposed opposite thebase 438, and the second seal 428 b may include a sealing surface 444opposite the base 440. Accordingly, the sealing surface 442 of the firstseal 428 a may engage contact, interlock, and/or otherwise mate with thesealing surface 444 of the second seal 428 b when the fitting 402 isremovably attached to the adapter 402 to form a fluid-tight sealtherewith.

Further, the body 420 of the adapter 404 may also include a centralopening (as shown more clearly in FIG. 2 ) at least partially formed byan inner wall 446 (FIG. 4 a ) of the body 420. In such examples, thelongitudinal axis X of the body 420 may extend substantially centrallythrough the central fluid passage of the adapter 404 formed by thesubstantially cylindrical inner wall 446 of the adapter 404. The centralopening, inner wall 446, and central fluid passage of the adapter 404may be substantially similar to the central opening, inner wall 344, andcentral fluid passage described above with respect to FIG. 3 . In suchexamples, a substantially cylindrical outer wall 448 of the channel 416may be disposed adjacent and/or at least partly in contact with theinner wall 446 of the adapter 404 when the fitting 402 is removablyattached to the adapter 404.

As shown in FIG. 5 , an example system 500 or other environment of thepresent disclosure may include a fitting 502 that is substantiallysimilar to the fitting 402, and/or may include a blood pressure cuffadapter 504 that is substantially similar to the blood pressure cuffadapter 404. In such systems 500, the example fitting 502 may beremovably attachable to such an adapter 504, and in such a system 500,the stands 412 a, 412 b described above with respect to FIG. 4 may beomitted. Instead, the fitting 502 may include a pair of arms extendingfrom the body of the fitting 502, and the fitting 502 may also include arelatively flexible diaphragm at a substantially central top portion ofthe body. Applying a downward force to the diaphragm while applying anupward force to one or more grips associated with the arms may assist inremovably attaching the fitting 502 to the adapter 504 and/or detachingthe fitting 502 from the adapter 504. In example embodiments, any of thestructures, functions, and/or other aspects of the various fittingsdescribed herein may be included in the fitting 502. Likewise, any ofthe structures, functions, and/or other aspects of the various adaptersdescribed herein may be included in the adapter 504. Further, one ormore of the structures, functions, and/or features of the fitting 502,and/or of the adapter 504, may be incorporated into any of the fittingsor adapters of the present disclosure.

In the example system 500, various components of the fitting 502 may besubstantially similar to corresponding components of the fitting 402,and various components of the adapter 504 may be substantially similarto corresponding components of the adapter 404. For example, the fitting502 may include a substantially rigid body 506, and one or more arms 508a, 508 b extending from the body 506. The first and second arms 508 a,508 b may also include respective shelves 510 a, 510 b formed atrespective distal ends of the arms 508 a, 508 b. In the embodiment ofFIG. 5 , the arms 508 a, 508 b may be movably connected to the body 506via a direct connection with the body 506 and/or via one or more posts512 a, 512 b or other pieces of material extending substantiallylaterally from the body 506 to proximal portions of the respective arms508 a, 508 b. As can be seen from FIG. 5 , the first and second shelves510 a, 510 b may extend substantially perpendicularly from therespective arms 508 a, 508 b. In particular, such first and secondshelves 510 a, 510 b may include one or more surfaces (e.g., a topsurface, a bottom surface opposite the top surface, a side surface,etc.), extending substantially perpendicularly from the respective arms508 a, 508 b, and such surfaces may be configured to mate with acorresponding surface of the adapter 504 in order to removably attachthe fitting 502 to the adapter 504.

At least one of the body 506, posts 512 a, 512 b, arms 508 a, 508 b,shelves 510 a, 510 b, and/or other components of the fitting 502 may bemade from any of the materials described above with respect to the body48. In any such examples, the shape, size, materials, and/or otherconfiguration of the posts 512 a, 512 b may provide for movement of thecorresponding arms 508 a, 508 b and/or shelves 510 a, 510 b relative tothe body 506 when force is applied to respective grips 514 a, 514 bconnected to the arms 508 a, 508 b. For example, the fitting 502 mayinclude a diaphragm 536 disposed at a substantially central top portion538 of the body 506. In such examples, the diaphragm 536 may comprise arelatively thin portion of the body 506, and the location, thickness,and/or other configurations of the diaphragm 536 may enable the body 506to flex when a downward force in the direction of arrow 542 is appliedto the diaphragm 536. In such examples, the body 506 may also include asubstantially rounded, substantially hollow internal portion 540disposed opposite the top portion 538. Such a substantially hollowinternal portion 540 may be configured to increase the flexibility ofthe body 506. In particular, the substantially hollow internal portion540 may increase the distance and/or degree to which the body 506 flexeswhen a downward force in the direction of arrow 542 is applied to thediaphragm 536. In use, a healthcare practitioner may apply an upwardforce in the direction of arrow 544 to one or both of the grips 514 a,514 b while, at the same time, applying a downward force to thediaphragm 536 in the direction of arrow 542. The application of one ormore such forces may cause one or both of the shelves 510 a, 510 b tomove laterally away from a central longitudinal axis Z (FIG. 2 ) of thefitting 502. Such movement may enable the fitting 502 to be removablyattached to the blood pressure cuff adapter 504, and may also enable thefitting 502 to be detached from the adapter 504. It is understood that,in an alternate embodiment, the grips 514 a, 514 b may be replaced witha substantially annular, substantially circular, and/or substantiallydisc-shaped structure substantially surrounding the diaphragm 536 andconfigured to receive the upward force described above in the directionof arrow 544.

The fitting 502 may also include one or more extensions, passages,and/or other like channels 516 extending from the body 506. In someexamples, the channel 516 may extend substantially along thelongitudinal axis Z (FIG. 2 ) of the fitting 502, and the longitudinalaxis Z may extend substantially centrally through the channel 516. Thechannel 516 may form an opening 518 configured to permit the passage ofair or other fluids into the cuff 12 via the fitting 502, and/or tootherwise fluidly connect the fitting 502 with the cuff 12, when thefitting 502 is removably attached to the adapter 504. The fitting 502may further include a central fluid passage 519 extending at leastpartially through the body 506. For example, the channel 516 and/or thesubstantially hollow internal portion 540 may form at least part of thecentral fluid passage 519 of the fitting 502, and the longitudinal axisZ (FIG. 2 ) may extend substantially centrally through at least part ofthe central passage 519. In such examples, the opening 518 of thechannel 516 may comprise an opening of the central passage 519.

As noted above with respect to the adapter 50 of FIG. 2 , the adapter504 may include a substantially rigid body 520 that is at least partlyconnected to the cuff 12. For example, the body 520 may include a distalportion 521 extending outwardly from the outer surface 54 of the cuff12. The body 520 may also include a proximal portion 535 embedded withinthe cuff 12 and/or extending inwardly from the outer surface 54. In someexamples, a top surface of the proximal portion 535 may extend at leastpartly along and/or may be connected to an inner surface of the cuff 12disposed opposite the outer surface 54. The body 520 of the adapter 504may be made from any of the materials described above with respect to,for example, the fitting 42. In some examples, the adapter 504 may bemade from more than one such material. For example, one or morecomponents or other parts of the distal portion 521 may be made from afirst material, and one or more components or other parts of theproximal portion 535 may be made from a second material different fromthe first material. As noted above with respect to the adapter 50 ofFIG. 2 , in such examples, the use of such first and second materialsmay result in the various components or other parts of the body 520having different rigidities, durabilities, sealing characteristics,and/or other properties.

The distal portion 521 of the adapter 504 may include an annular ring522 having a top surface 526 and a ridge 524 disposed opposite the topsurface 526. The ridge 524 may comprise at least part of a bottomsurface of the ring 522. In such examples, at least part of the ridge524 and/or at least another part of the bottom surface of the ring 522may be configured to mate with the shelves 510 a, 510 b of the fitting502 to assist in retaining the fitting 502 and/or otherwise removablyattaching the fitting 502 to the adapter 504. In some examples, at leastpart of the ridge 524 and/or at least another part of the bottom surfaceof the ring 522 may extend substantially perpendicular to a longitudinalaxis X of the body 520. Additionally, the adapter 504 may include asubstantially cylindrical sidewall extending from the ridge 524 to thetop surface of the proximal portion 535. Such a sidewall may space theridge 524 from the top surface of the proximal portion 535 such that theshelves 510 a, 510 b of the fitting 502 may have room to mate with theridge 524 beneath the ring 522.

The top surface 526 of the ring 522 may be substantially convex,substantially concave, substantially curved, substantially tapered,and/or any other configuration in order to assist in removably attachingthe fitting 502 to the adapter 504. In some examples, the top surface526 of the ring 522 may comprise a convex surface extending radiallyaway from the longitudinal axis X of the body 520 from a distal end 530of the top surface 526 to a proximal end 532 of the top surface 526. Insuch examples, the curved top surface 526 may comprise a camming surfacealong which at least part of the arms 508 a, 508 b and/or othercomponents of the fitting 502 may slide as the fitting 502 is removablyattached to the adapter 504.

The system 500 may also include one or more O-rings, gaskets, and/orother seals 528 configured to form a substantially fluid-tight sealbetween the fitting 502 and the adapter 504 when the fitting 502 isremovably attached to the adapter 504. For example, at least one seal528 may be attached to, adhered to, embedded substantially within,and/or otherwise connected to either an outer surface 534 of the fitting502 or to the top surface 526 of the ring 522 to facilitate forming sucha fluid-tight seal. In the example system 500 of FIG. 5 , at least part(e.g., a base) of the seal 528 may be disposed within an annular grooveformed by the top surface 526 of the ring 522. In such examples, theseal 528 may engage the outer surface 534 of the fitting 502 proximate aperimeter and/or outer wall of the channel 516 to form a substantiallyfluid-tight seal with the fitting 502 when the fitting 502 is removablyattached to the adapter 504. Alternatively, the seal 528 may be attachedto, adhered to, embedded substantially within, and/or otherwiseconnected to the outer surface 534 of the fitting 502, and may beconfigured to engage the top surface 526 of the adapter 504 to form sucha substantially fluid-tight seal.

Further, the body 520 of the adapter 504 may also include a centralopening (as shown more clearly in FIG. 2 ) at least partially formed byan inner wall of the body 520. In such examples, the longitudinal axis Xof the body 520 may extend substantially centrally through the centralfluid passage of the adapter 504 formed by the substantially cylindricalinner wall of the adapter 504. The central opening, inner wall, andcentral fluid passage of the adapter 504 may be substantially similar tothe central opening, inner wall 344, and central fluid passage describedabove with respect to FIG. 3 .

As shown in FIGS. 6 a and 6 b , an example system 600 or otherenvironment of the present disclosure may include a fitting 602 that isconfigured to be removably attached to a blood pressure cuff adapter 604by movement of the fitting 602 in a first direction substantiallyparallel to the top surface 54 of the cuff 12. In such examples, thefitting 602 may also be configured to be detached from the adapter 604by moving the fitting 602 in a second direction substantially parallelto the top surface 54 of the cuff opposite the first direction. Inexample embodiments, any of the structures, functions, and/or otheraspects of the various fittings described herein may be included in thefitting 602. Likewise, any of the structures, functions, and/or otheraspects of the various adapters described herein may be included in theadapter 604. Further, one or more of the structures, functions, and/orfeatures of the fitting 602, and/or of the adapter 604, may beincorporated into any of the fittings or adapters of the presentdisclosure.

In the example system 600, various components of the fitting 602 may besubstantially similar to corresponding components of, for example, thefitting 402, and various components of the adapter 604 may besubstantially similar to corresponding components of, for example, theadapter 404. For example, the fitting 602 may include a substantiallyrigid body 606, and one or more arms 608 a, 608 b extending from thebody 606. The first and second arms 608 a, 608 b may also includerespective shelves 610 a, 610 b formed at respective distal ends of thearms 608 a, 608 b. In the embodiment of FIGS. 6 a and 6 b , the arms 608a, 608 b may be movably connected to the body 606 via a directconnection with the body 606 and/or via one or more posts 612 a, 612 bor other pieces of material extending substantially laterally from thebody 606 to the respective arms 608 a, 608 b. As can be seen from atleast FIG. 6 a , the first and second shelves 610 a, 610 b may extendsubstantially perpendicularly from the respective arms 608 a, 608 b. Inparticular, such first and second shelves 610 a, 610 b may include oneor more surfaces (e.g., a top surface, a bottom surface opposite the topsurface, a side surface, etc.), extending substantially perpendicularlyfrom the respective arms 608 a, 608 b, and such surfaces may beconfigured to mate with a corresponding surface of the adapter 604 inorder to removably attach the fitting 602 to the adapter 604.

At least one of the body 606, posts 612 a, 612 b, arms 608 a, 608 b,shelves 610 a, 610 b, and/or other components of the fitting 602 may bemade from any of the materials described above with respect to the body48. In any such examples, the shape, size, materials, location, and/orother configuration of the posts 612 a, 612 b may provide for movementof the corresponding arms 608 a, 608 b and/or shelves 610 a, 610 brelative to the body 606 when force is applied to respective grips 614a, 614 b associated with the arms 608 a, 608 b. For example, ahealthcare practitioner may apply an inward force (e.g., in a directiontoward the body 606 of the fitting 602) to one or both of the grips 614a, 614 b. The application such an inward force to the grip 614 a maycause the arm 608 a to pivot about the post 612 a, thereby causing theshelf 610 a to move laterally away from the body 606 and/or a centrallongitudinal axis of the fitting 602. Likewise, the application such aninward force to the grip 614 b may cause the arm 608 b to pivot aboutthe post 612 b, thereby causing the shelf 610 b to move laterally awayfrom the body 606 and/or a central longitudinal axis of the fitting 602.Such movement of the shelves 610 a, 610 b may enable the fitting 602 tobe removably attached to the blood pressure cuff adapter 604 when thefitting 602 is moved in a first direction of arrow 644 substantiallyparallel to the top surface 54 of the cuff 12. Similarly, such movementof the shelves 610 a, 610 b may enable the fitting 602 to be detachedfrom the adapter 604 when the fitting 602 is moved in a second directionof arrow 644 opposite the first direction and substantially parallel tothe top surface 54 of the cuff 12.

The fitting 602 may also include one or more extensions, passages,and/or other like channels 616 extending from the body 606. In someexamples, the channel 616 may extend substantially along thelongitudinal axis of the fitting 602, and the longitudinal axis mayextend substantially centrally through the channel 616. The channel 616may form an opening 618 configured to permit the passage of air or otherfluids into the cuff 12 via the fitting 602, and/or to otherwise fluidlyconnect the fitting 602 with the cuff 12, when the fitting 602 isremovably attached to the adapter 604. The fitting 602 may furtherinclude a central fluid passage 619 extending at least partially throughthe body 606. For example, the channel 616 may form at least part of thecentral fluid passage 619 of the fitting 602, and the longitudinal axisof the fitting 602 may extend substantially centrally through at leastpart of the central passage 619. In such examples, the opening 618 ofthe channel 616 may comprise an opening of the central passage 619.

As noted above with respect to the adapter 50 of FIG. 2 , the adapter604 may include a substantially rigid body 620 that is at least partlyconnected to the cuff 12. For example, the body 620 may include a distalportion 621 extending outwardly from the outer surface 54 of the cuff12. The body 520 may also include a proximal portion 636 embedded withinthe cuff 12 and/or extending inwardly from the outer surface 54. In someexamples, a top surface of the proximal portion 636 may extend at leastpartly along and/or may be connected to an inner surface of the cuff 12disposed opposite the outer surface 54. As shown in FIG. 6 b , the body620 may include a first wall 636 extending substantially parallel to thetop surface 54 of the cuff 12 and/or to the top surface of the proximalportion 635. The body 620 may also include a second wall 638 oppositeand extending substantially parallel to the first wall 636. In suchexamples, the body 620 may further include a pair of sidewalls extendingfrom the first wall 636 to the second wall 638, and side surfaces 624 a,624 b (e.g., outer surfaces 624 am 624 b of the body 620) of suchsidewalls are illustrated in at least FIG. 6 a . Additionally, the body620 may include a third wall 640 extending substantially perpendicularto the top surface 54 of the cuff 12 and/or to the top surface of theproximal portion 635. The body 620 may also include a fourth wall 642opposite and extending substantially parallel to the third wall 640. Insome examples, the body 620 may further include a pair of sidewallsextending from the third wall 640 to the fourth wall 642.

In any of the examples described herein, the body 620 may also include afirst longitudinal axis X extending substantially centrally through afirst section of the distal portion 621 formed, at least in part, by thefirst and second walls 636, 638. For example, the first and second walls636, 638 may extend substantially parallel to the first longitudinalaxis X, and the first and second walls 636, 638 may define at least partof a first central fluid passage 630 of the distal portion 621. The body620 may also include a second longitudinal axis Y extendingsubstantially centrally through a second section of the distal portion621 formed, at least in part, by the third and fourth walls 640, 642.For example, the third and fourth walls 640, 642 may extendsubstantially parallel to the second longitudinal axis Y, and the thirdand fourth walls 640, 642 may define at least part of a second centralfluid passage 631 of the distal portion 621. In such examples, the firstlongitudinal axis X may extend substantially perpendicular to the secondlongitudinal axis Y. Further, the first fluid passage 630 of the adapter620 may be fluidly connected to the second fluid passage 631 of theadapter 620. In such examples, the first longitudinal axis X may extendsubstantially parallel to the top surface 54 of the cuff 12, and mayextend substantially centrally through the first central passage 630.Additionally, the second longitudinal axis Y may extend substantiallyperpendicular to the top surface 54 of the cuff 12, and may extendsubstantially centrally through the second central passage 631.

The body 620 of the adapter 604 may be made from any of the materialsdescribed above with respect to, for example, the fitting 42. In someexamples, the adapter 604 may be made from more than one such material.For example, one or more components or other parts of the distal portion621 may be made from a first material, and one or more components orother parts of the proximal portion 635 may be made from a secondmaterial different from the first material. As noted above with respectto the adapter 50 of FIG. 2 , in such examples, the use of such firstand second materials may result in the various components or other partsof the body 620 having different rigidities, durabilities, sealingcharacteristics, and/or other properties.

The distal portion 621 of the adapter 604 may include a ring 622disposed at an open end of the distal portion 621. In such examples, thering 622 may form an opening of the first central passage 630, and thering 622 may be formed, at least in part, by distal ends of the firstwall 636, the second wall 638, and the sidewalls extending from thefirst wall 636 to the second wall 638. The ring 622, and the openingformed thereby, may be shaped, sized, and/or otherwise configured toallow at least part of the channel 616 to pass therethrough when thefitting 602 is removably attached to the adapter 604. In such examples,the channel 616 may pass through the ring 622 and/or the opening, and atleast part of the channel 616 may be disposed within the first centralpassage 630 of the adapter 604 when the fitting 602 is removablyattached to the adapter 604. In such examples, the system 600 may alsoinclude one or more O-rings, gaskets, and/or other seals 628 configuredto form a substantially fluid-tight seal between the fitting 602 and theadapter 604 when the fitting 602 is removably attached to the adapter604. For example, at least one seal 628 may be attached to, adhered to,embedded substantially within, and/or otherwise connected to either anouter surface 634 of the fitting 602 or to a corresponding distal and/orother outer surface of the ring 622 to facilitate forming such afluid-tight seal. In the example system 600, at least part (e.g., abase) of the seal 628 may be disposed within a groove formed by thedistal and/or other outer surface of the ring 622. In such examples, theseal 628 may engage the outer surface 634 of the fitting 602 proximate aperimeter and/or outer wall of the channel 616 to form a substantiallyfluid-tight seal with the fitting 602 when the fitting 602 is removablyattached to the adapter 604. Alternatively, the seal 628 may be attachedto, adhered to, embedded substantially within, and/or otherwiseconnected to the outer surface 634 of the fitting 602, and may beconfigured to engage the distal and/or other outer surface of the ring622 to form such a substantially fluid-tight seal.

The body 620 of the adapter 604 may also include a first ridge 624 aformed on the side surface 626 a (e.g., the outer surface of the firstsidewall extending from the first wall 636 to the second wall 638) ofthe distal portion 621, and a second ridge 624 b formed on the sidesurface 626 b (e.g., the outer surface of the second sidewall extendingfrom the first wall 636 to the second wall 638) of the distal portion621. The first ridge 624 a may be configured to mate with the firstshelf 610 a of the fitting 602 to assist in retaining the fitting 602and/or otherwise removably attaching the fitting 602 to the adapter 604.Likewise, the second ridge 624 b may be configured to mate with thesecond shelf 610 b of the fitting 602 to assist in retaining the fitting602 and/or otherwise removably attaching the fitting 602 to the adapter604. In some examples, at least part of the first ridge 624 a may extendsubstantially perpendicular to the side surface 626 a of the body 620,and at least part of the second ridge 624 b may extend substantiallyperpendicular to the side surface 626 b of the body 620. As shown inFIG. 6 a , at least one of the ridges 624 a, 624 b may includecorresponding camming surfaces 648 a, 648 b extending at an angle (e.g.,an acute angle) from the side surfaces 626 a, 626 b of the body 620 toends of the respective ridges 624 a, 624 b. Such camming surfaces 648 a,648 b may be shaped, sized, located, and/or otherwise configured suchthat at least part of the arms 608 a, 608 b and/or other components ofthe fitting 602 may slide along the camming surfaces 648 a, 648 b as thefitting 602 is removably attached to the adapter 604. For example, inother embodiments such camming surfaces 648 a, 648 b may besubstantially convex, substantially concave, substantially curved,substantially tapered, and/or any other configuration in order to assistin removably attaching the fitting 602 to the adapter 604.

As shown in FIGS. 7 a-7 e , in some example systems 700 or otherembodiments of the present disclosure a fitting 702 and/or a bloodpressure cuff adapter 704 may include one or more features or otherstructural components configured to assist a healthcare practitioner inaligning the fitting 702 with the adapter 704 as the fitting 702 isbeing removably attached to the adapter 704. In example embodiments, anyof the structures, functions, and/or other aspects of the variousfittings described herein may be included in the fitting 702. Likewise,any of the structures, functions, and/or other aspects of the variousadapters described herein may be included in the adapter 704. Further,one or more of the structures, functions, and/or features of the fitting702, and/or of the adapter 704, may be incorporated into any of thefittings or adapters of the present disclosure.

In the example system 700, various components of the fitting 702 may besubstantially similar to corresponding components of, for example, thefitting 402, and various components of the adapter 704 may besubstantially similar to corresponding components of, for example, theadapter 704. For example, the fitting 702 may include a substantiallyrigid body 706, and one or more arms 708 a, 708 b extending from thebody 706. The first and second arms 708 a, 708 b may also includerespective shelves 710 a, 710 b formed at respective distal ends of thearms 708 a, 708 b.

As can be seen in at least FIG. 7 a ,the first and second shelves 710 a, 710 b may extend substantiallyperpendicularly from the respective arms 708 a, 708 b. In particular,such first and second shelves 710 a, 710 b may include one or moresurfaces (e.g., a top surface, a bottom surface opposite the topsurface, a side surface, etc.), extending substantially perpendicularlyfrom the respective arms 708 a, 708 b, and such surfaces may beconfigured to mate with a corresponding surface of the adapter 704 inorder to removably attach the fitting 702 to the adapter 704.

At least one of the body 706, stands 712 a, 712 b, arms 708 a, 708 b,shelves 710 a, 710 b, and/or other components of the fitting 702 may bemade from any of the materials described above with respect to the body48. In any such examples, the shape, size, materials, and/or otherconfiguration of the stands 712 a, 712 b may provide for movement of thecorresponding arms 708 a, 708 b and/or shelves 710 a, 710 b relative tothe body 706 when force is applied to respective grips 714 a, 714 bassociated with the stands 712 a, 712 b. Such movement may enable thefitting 702 to be removably attached to the blood pressure cuff adapter704, and may also enable the fitting 702 to be detached from the adapter704.

The fitting 702 may also include one or more extensions, passages,and/or other like channels 716 extending from the body 706. In someexamples, the channel 716 may extend substantially along thelongitudinal axis Z (FIG. 2 ) of the fitting 702, and the longitudinalaxis Z may extend substantially centrally through the channel 716. Thechannel 716 may form an opening 718 configured to permit the passage ofair or other fluids into the cuff 12 via the fitting 702, and/or tootherwise fluidly connect the fitting 702 with the cuff 12, when thefitting 702 is removably attached to the adapter 704. The fitting 702may further include a central fluid passage 719 extending at leastpartially through the body 706. For example, the channel 716 may form atleast part of the central fluid passage 719 of the fitting 702, and thelongitudinal axis Z (FIG. 2 ) may extend substantially centrally throughat least part of the central passage 719. In such examples, the opening718 of the channel 716 may comprise an opening of the central passage719.

For example, the body 720 may include a distalportion 721 extending outwardly from the outer surface 54 of the cuff12. The body 720 may also include a proximal portion 719 embedded withinthe cuff 12 and/or extending inwardly from the outer surface 54. In someexamples, a top surface of the proximal portion 719 may extend at leastpartly along and/or may be connected to an inner surface of the cuff 12disposed opposite the outer surface 54. The body 720 of the adapter 704may be made from any of the materials described above with respect to,for example, the fitting 42. In some examples, the adapter 704 may bemade from more than one such material. For example, one or morecomponents or other parts of the distal portion 721 may be made from afirst material, and one or more components or other parts of theproximal portion 719 may be made from a second material different fromthe first material. As noted above with respect to the adapter 50 ofFIG. 2 , in such examples, the use of such first and second materialsmay result in the various components or other parts of the body 720having different rigidities, durabilities, sealing characteristics,and/or other properties.

The ridge 724 may comprise at least part of a bottomsurface of the ring 722. In such examples, at least part of the ridge724 and/or at least another part of the bottom surface of the ring 722may be configured to mate with the shelves 710 a, 710 b of the fitting702 to assist in retaining the fitting 702 and/or otherwise removablyattaching the fitting 702 to the adapter 704. In some examples, at leastpart of the ridge 724 and/or at least another part of the bottom surfaceof the ring 722 may extend substantially perpendicular to a longitudinalaxis X of the body 720. Additionally, the adapter 704 may include asubstantially cylindrical sidewall extending from the ridge 724 to thetop surface of the proximal portion 719. Such a sidewall may space theridge 724 from the top surface of the proximal portion 719 such that theshelves 710 a, 710 b of the fitting 702 may have room to mate with theridge 724 beneath the ring 722.

The top surface 726 of the ring 722 may be substantially convex,substantially concave, substantially curved, substantially tapered,and/or any other configuration in order to assist in removably attachingthe fitting 702 to the adapter 704. In some examples, the top surface726 of the ring 722 may comprise a convex surface extending radiallyaway from the longitudinal axis X of the body 720 from a distal end 730of the top surface 726 to a proximal end 732 of the top surface 726. Insuch examples, the curved top surface 726 may comprise a camming surfacealong which at least part of the arms 708 a, 708 b and/or othercomponents of the fitting 702 may slide as the fitting 702 is removablyattached to the adapter 704.

In example embodiments, the ring 722 may also include a groove 728extending at least partly (and, in some examples, completely) around thelongitudinal axis X, and being shaped, sized, located, and/or otherwiseconfigured to accept a member 734 and/or other structural feature of theadapter 702. As shown in at least FIG. 7 a , such a member 734 mayextend (e.g., substantially perpendicularly) from an outer surface 736of the fitting 702 disposed opposite and/or facing the top surface 726when the fitting 702 is removably attached to the adapter 704. Themember 734 may comprise a shaft, pin, rod, rib, ring, flange, detent,and/or other extension of the body 706, and the member 734 may be usefulin laterally and/or otherwise aligning the fitting 702 with the adapter704 when removably attaching the fitting 702 to the adapter 704. Forexample, the groove 728 and the member 734 may be positioned and/orotherwise configured such that disposing at least part of the member 734within the groove 728 when removably attaching the fitting 702 to theadapter 704 may cause the longitudinal axis Z of the fitting 702 (FIG. 2) to be collinear with the longitudinal axis X of the adapter 704. Themember 734 may be substantially cylindrical, substantially cube-shaped,substantially V-shaped, substantially arcuate, substantially annular,and/or any other shape to assist in aligning the fitting 702 with theadapter 704. Additionally, in any of the example embodiments describedherein the member 734 may be shaped, sized, dimensioned, located, and/orotherwise configured to minimize and/or substantially eliminate lateralmovement of the fitting 702 relative to the adapter 704 when the fitting702 is removably attached to the adapter 704. In any such examples, themember 734 may be shaped, sized, dimensioned, located, and/or otherwiseconfigured to provide additional rigidity, support, and/or stability tothe removable connection between the fitting 702 and the adapter 704.Further, in any of the example embodiments described herein having amember and a groove, the member (e.g., the member 734) may alternativelycomprise an extension and/or other component of the adapter (e.g., theadapter 704), and in such embodiments the groove (e.g., the groove 728)may be formed by and/or may comprise a component of the fitting (e.g.,the fitting 702). Additionally, in any of the embodiments describedherein having a member and a groove, the member (e.g., the member 734)may comprise a plurality of members (e.g., a plurality of arcuatesegments, etc.) spaced substantially circumferentially about, forexample, the longitudinal axis Z (FIG. 2 ) of the fitting 702. Further,while FIG. 7 a illustrates the groove 728 being disposed on and/orformed by the top surface 726, in other examples, the groove 728 may bedisposed on, disposed proximate, and/or formed by a radially outermostportion of the ring 722.

In any of the embodiments herein, a first component of the fitting 702may be configured to mechanically interlock with (e.g., a snap-fit, afriction fit, a meshing, and/or any other type of interlock) acorresponding second component of the adapter 704. For example, in someembodiments a component of the member 734 may form a snap-fit and/orother interlocking fit with the groove 728 of the adapter 704. In otherembodiments, at least part of the channel 716 may interlock with atleast part of the portion 719 of the adapter 704 when the fitting 702 isremovably attached to the adapter 704.

The system 700 may also include one or more O-rings, gaskets, and/orother seals 737 configured to form a substantially fluid-tight sealbetween the fitting 702 and the adapter 704 when the fitting 702 isremovably attached to the adapter 704. For example, at least one seal737 may be attached to, adhered to, embedded substantially within,disposed adjacent to, and/or otherwise connected to a substantiallycylindrical inner wall 738 of the adapter 704 to facilitate forming sucha fluid-tight seal. In such examples, the seal 737 may engage an outerwall 740 of the channel 716 (e.g., an outer surface of the outer wall740) to form a substantially fluid-tight seal with the fitting 702 whenthe fitting 702 is removably attached to the adapter 704.

As shown in at least FIG. 7 b , the adapter 704 may also include acentral opening 742 at least partially formed by a surface of the innerwall 738. In such examples, the longitudinal axis X (FIG. 7 a ) of thebody 720 may extend substantially centrally through a central fluidpassage of the adapter 704 formed by the substantially cylindrical innerwall 738. The central opening 742, inner wall 738, and central fluidpassage of the adapter 704 may be substantially similar to the centralopening, inner wall 344, and central fluid passage described above withrespect to FIG. 3 . Further, as shown in the top view of FIG. 7 b , insome examples the groove 728 may be disposed on the top surface 726between (e.g., substantially centrally between) the proximal end 732 andthe distal end 730 of the top surface 726. Additionally, in someexamples the groove 728 may include at least one detent 744 configuredto contact the member 734 when the fitting 702 is removably attached tothe adapter 704. It is understood that in at least the systems describedherein with respect to FIGS. 1-5, 7 a-7 e, and 10, the fitting may berotatable about the longitudinal axis X of the adapter 704 in theclockwise direction of arrow 746 and in the counter clockwise directionof arrow 748. In such examples, the one or more detents 744 disposedwithin the groove 728 may be shaped, sized, located, and/or otherwiseconfigured to contact the member 734 as the fitting 702 is rotated aboutthe longitudinal axis X of the adapter 704. The one or more detents 744may be substantially dome-shaped, substantially ramp-shaped, and/or anyother shape to assist in at least partially restricting rotation of thefitting 702 about the longitudinal axis X of the adapter 704 when themember 734 contacts the one or more detents 744.

As shown in at least FIG. 7 c , in some examples the groove 728 mayinclude at least one wall 750 extending substantially parallel to thelongitudinal axis X. In such examples, the wall 750 may prohibit 360degree rotation of the fitting 702 about the longitudinal axis X of theadapter 704 when the fitting 704 is removably attached to the adapter702. For example, the wall 750 may block rotation of the fitting 702about the longitudinal axis X of the adapter 704 when the member 734contacts the wall 750. Although the example embodiment of FIG. 7 cillustrates a single wall 750 disposed within the groove 728, in furtherexamples, two or more walls 750 may be disposed the groove 728. In anyof the examples described herein, the one or more walls 750 may have awidth and/or a height substantially equal to a corresponding widthand/or height of the groove 728.

The cross-sectional view of FIG. 7 d illustrates portions of the fitting702 and the adapter 704 in more detail. For example, as noted above, thegroove 728 may have any desired width W and/or height H in order toaccommodate the member 734. For example, the groove 728 may include abase 752, a first sidewall 754 extending substantially perpendicularlyfrom the base 752, and a second sidewall 756 opposite the first sidewall754 and extending substantially perpendicularly from the base 752. Insuch examples, the first and second sidewalls 754, 756 may extend fromthe base 752 to the top surface 726, and the height H of the groove 728may comprise either a height H of the first sidewall 754 or a height Hof the second sidewall 756. In any of the examples described herein, oneor more of the detents 744 described above may be disposed on the base752, the first sidewall 754, or the second sidewall 756.

In some examples, the height H of the groove 728 may be substantiallyconstant. In other examples, on the other hand, the groove 728 may havea variable height H along at least a portion of the groove 728. Forexample, as shown in FIG. 7 d the base 752 of the groove 728 may have atleast one trough 757 and at least one peak 758. In such examples, thetrough 757 may comprise a first portion of the groove 728 having thelargest height H, and the peak 758 may comprise a second portion of thegroove 728 having the smallest height H. For instance, in such examplesthe peak 758 formed by the base 752 may be disposed axially closer tothe top surface 726 of the ring 722 than the trough 757 formed by thebase 752. In such examples, the variability in the height H of thegroove 728 (e.g., the decrease in height H from the trough 757 to thepeak 758) may assist the user in detaching the fitting 702 from theadapter 704. For example, the member 734 may slidably engage and/orotherwise move substantially along the base 752 as the fitting 702 isrotated about the longitudinal axis X of the adapter 704. In suchexamples, engagement between the member 734 and the base 752 as themember 734 moves from a first location proximate the trough 757 to asecond location proximate the peak 758 may assist in moving the fitting702 in an upward direction away from the adapter 704. Such movement mayassist a healthcare practitioner in detaching the fitting 702 from theadapter 704.

In such examples, the member 734 may also be shaped, sized, and/orotherwise configured to assist a healthcare practitioner in detachingthe fitting 702 from the adapter 704. For example, the member 734 mayinclude a base 764, a first sidewall 766 extending substantiallyperpendicularly from the base 764, and a second sidewall 768 oppositethe first sidewall 766 and extending substantially perpendicularly fromthe base 764. In such examples, the first and second sidewalls 766, 768may extend from the base 764 to the outer surface 736. The member 734may also have a height H′ substantially equal to the height H of thegroove 728, and a width W′ substantially equal to the width W of thegroove 728. It is understood that in some examples, the height H′ may bemarginally less than the height H, and the width W′ may be marginallyless than the width W to minimize and/or substantially eliminatefriction and/or resistance caused by the member 734 contacting one orboth of the sidewalls 754, 756. Further, the sidewall 756 of the groove728 may be disposed a distance L from the inner wall 738, and thesidewall 766 may be disposed a distance L′ from the outer wall 740 ofthe channel 716 substantially equal to the distance L.

As shown in FIG. 7 e , in further examples, the fitting 702 may includeone or more sensors configured to determine a distance between at leastpart of the fitting 702 and a corresponding part of the adapter 704.Additionally or alternatively, in some examples the one or more sensorsmay be configured to read information from a corresponding component ofthe adapter 704 and/or otherwise assist in identifying the adapter 704.For example, the fitting 702 may include a capacitance sensor, aproximity sensor, a light sensor, RFID sensor, a barcode reader, and/orany other sensor 762 connected thereto. In some examples, the sensor 762may be disposed on, embedded substantially within, and/or otherwiseconnected to the member 734, such as at a distal end of the member 734.In such examples, the fitting 704 may include a corresponding conductor,layer of reflective paint or ink, RFID tag, barcode, and/or otherfeature 760. In such examples, the feature 760 may be disposed anywhereon and/or within the adapter 704 such that the feature 760 is located atleast partly within a field of view of the sensor 762 when the fitting702 is removably attached to the adapter 704. For example, inembodiments in which the sensor 762 is disposed on embeddedsubstantially within, and/or otherwise connected to the member 734, suchas at a distal end of the member 734, the feature 760 may be disposed onembedded substantially within, and/or otherwise connected to the base752 of the groove 728 or at least one of the sidewalls 754, 756.Further, although FIG. 7 e illustrates the sensor 762 being connected tothe fitting 702 and the feature 760 being connected to the adapter 704,in other examples, this configuration may be reversed such that thesensor 762 is connected to the adapter 704 and the feature 760 isconnected to the fitting 702.

In any of the examples described herein, the sensor 762 may be operablyconnected to and/or otherwise in communication with the controller 20described above. For example, the sensor 762 may be configured todetermine, among other things, a distance between (e.g., a proximity)the distal end of the member 734 and the base 752 of the groove 728. Insuch examples, various cuffs 12 may include adapters 704 having grooves728 of respective known heights H based on a desired application,desired intended use (e.g., child, adult, bariatric patient, elderlypatient, etc.), and/or desired fitting 702 with which the particularcuff 12 should be used. For example, a cuff 12 manufactured by anexample first manufacturer may be tuned and/or otherwise designed to beused with fittings 702 manufactured by the same first manufacturer.Accordingly, the groove 728 of an adapter 704 connected to such anexample cuff 12 may have a known height H that is saved in the memory 24associated with the controller 20. In examples in which a correspondingfitting 702 manufactured by the same first manufacturer is removablyattached to the adapter 704, the sensor 762 may determine such a knownheight H and/or a corresponding known distance between (e.g., aproximity) the distal end of the member 734 and the base 752 of thegroove 728, and may send a signal including such information to thecontroller 20. Upon receipt of the signal, the controller 20 may comparesuch information to one or more known values corresponding to approvedfittings 702 manufactured by the first manufacturer, and the controller20 may identify a match based on such a comparison. In response, thecontroller 20 may cause a flow control device 770 operably connected tothe controller 20 to inflate and/or deflate the cuff 12 according tostandard operating flow rates and/or cuff pressures.

On the other hand, in examples in which a fitting 702 manufactured by asecond manufacturer (different from the first manufacturer of the cuff12) is removably attached to the adapter 704, the sensor 762 maydetermine a different height H and/or a different distance between thedistal end of the member 734 and the base 752 of the groove 728. Thesensor 762 may send a signal including such information to thecontroller 20, and the controller 20 may compare such information to oneor more known values corresponding to approved fittings 702 manufacturedby the first manufacturer, and the controller 20 may determine that nomatch exists based on such a comparison. In response, the controller 20may prohibit the flow control device 770 from inflating the cuff 12 ormay cause the flow control device 770 to inflate and/or deflate the cuff12 with significantly reduced (e.g., undesirably low) operating flowrates and/or cuff pressures. In this way, the sensor 762 and the feature760 illustrated in FIG. 7 e may be useful in preventing the use offittings 702 that do not match or correspond with a cuff having aparticular adapter 704. In such examples the sensor 762 and the feature760 illustrated in FIG. 7 e may also be useful in preventing the use ofcuffs 12 having adapters 704 that do not match or correspond with theparticular fittings 702.

In the same way, the height H described above, the width and/or innerdiameter of the groove 728, an outer diameter of the adapter 704, and/orany other characteristics of the cuff 12 may be read, sensed, and/orotherwise determined by the sensor 762, and such characteristics may beused to determine whether an age appropriate cuff 12 is being used. Asnoted above, in some examples the sensor 762 may comprise an RFIDreader, and in such examples, such characteristics may be read by thesensor 762 reading a corresponding RFID tag or other feature 760disposed within the groove 728. For example, in situations in which anadult cuff is being used on an adolescent or child patient, thecontroller 20 may determine (based on one or more signals from thesensor 762) that an age inappropriate cuff 12 is currently being used.Such signals may indicate that, for example, a sensed height H, width,and/or inner diameter of the groove 728 does not match a known height H,width, and/or inner diameter of a groove corresponding to an acceptablecuff (e.g., an adolescent cuff) for the particular patient. In response,the controller 20 may prohibit the flow control device 770 frominflating the cuff 12 or may cause the flow control device 770 toinflate and/or deflate the cuff 12 with significantly reduced (e.g.,undesirably low) operating flow rates and/or cuff pressures. It is alsounderstood that the location of the groove 728 (e.g., the radialdistance between the longitudinal axis X and one or more sidewalls ofthe groove 728) may also be sensed by the sensor 762 in a similarmanner, and such a location may also be used to determine whether thecuff 12 was manufactured by such a first manufacturer and/or whether thecuff 12 is appropriate for the age, demographics, or othercharacteristics of the patient.

In any of the examples described herein, the fitting 702 and/or theadapter 704 may be made, at least in part, from a substantiallytransparent or substantially translucent urethane or other such polymer.For example, the fitting 702 may be made from a substantiallytranslucent urethane, and may include one or more light-emitting diodes(LEDs) or other light sources operably connected to the controller 20.In such examples, the sensor 762 may be configured to determine whethera particular adapter 704 of a cuff matches or corresponds with aparticular fitting 702. If such an appropriate match is found, the oneor more LEDs may be controlled by the controller 20 to generate a firstvisual response (e.g., lighting up green or some other color) indicativeof the match. If such an appropriate match is not found, the one or moreLEDs may be controlled by the controller 20 to generate a second visualresponse (e.g., lighting up red or some other color) indicative thatsuch a match was not found.

Further, in some examples the sensor 762 and/or one or more additionalsensors operably connected to the adapter 704, the cuff 12, and/or thefitting 702 may be configured to determine an inflation pressure of thecuff 21, whether a leak is occurring, and/or other similar information.In any of the examples described herein, such sensors may provide one ormore signals to the controller 20 indicating such information, and thecontroller 20 may control the one or more LEDs to provide a visualresponse (e.g., blink, remain on, illuminate a desired color, etc.)based at least in part on such information. For example, the one or moreLEDs may be used to indicate that the cuff 12 has been inflated to apressure above a minimum pressure threshold, that the cuff 12 has beeninflated to a pressure above a maximum pressure threshold, that the cuff12 has a leak, that the cuff 12 has been left unattended for longer thana maximum time threshold, that an improper cuff 12 is being used, and/orother conditions.

In examples in which the controller 20 determines, based at least inpart on such signals from the one or more sensors, that the cuff 12 hasbeen inflated to an inflation pressure above a maximum threshold, thecontroller 20 may control a valve (e.g., a poppet valve, solenoid valve,etc.) fluidly connected to the cuff 12 to at least partly open in orderto decrease the inflation pressure of the cuff. In alternativeembodiments, the controller 12 may control the flow control device 770to reduce the inflation pressure of the cuff 12 to a desired level.

As shown in FIGS. 7 f and 7 g , in still further examples at least partof the ring 722 may be configured to mate with at least a portion of themember 734 to assist in, among other things, stabilizing the removableconnection between the fitting 702 and the adapter 704. For example, asshown in FIG. 7 f a radially inner portion of the ring 722 may beremoved to form a groove 728. In such examples, the groove 728 mayinclude a base 752 having a length L and extending substantiallyperpendicularly from the inner wall 738 of the adapter 704. Inparticular, the base 752 may extend radially outwardly from the innerwall 738. The groove 728 may also include a radially outermost sidewall754 extending substantially perpendicularly from the base 752. Forexample, the sidewall 754 may extend axially from the base 752 to thetop surface 726 of the ring 722. In such examples, the sidewall 754 maymate with and/or otherwise at least partially engage a radiallyoutermost surface of the member 734 when the fitting 702 is removablyattached to the adapter 704. Such engagement between the sidewall 754and the radially outermost surface of the member 734 may assist inminimizing and/or substantially eliminating lateral movement of thefitting 702 relative to the adapter 704 when the fitting 702 isremovably attached to the adapter 704.

Alternatively, as shown in FIG. 7 g a radially outer portion of the ring722 may be removed. In such examples, a groove formed in the ring 722may include a base 752 extending substantially perpendicularly relativeto the inner wall 738 of the adapter 704. Such a groove may also includea radially innermost sidewall 756 extending substantiallyperpendicularly from the base 752. For example, the sidewall 756 mayextend axially from the base 752 to the top surface 726 of the ring 722,and the sidewall 756 may be disposed a radial distance L from the innerwall 738. In such examples, the sidewall 756 may mate with and/orotherwise at least partially engage a radially innermost surface of themember 734 when the fitting 702 is removably attached to the adapter704. Such engagement between the sidewall 756 and the radially innermostsurface of the member 734 may assist in minimizing and/or substantiallyeliminating lateral movement of the fitting 702 relative to the adapter704 when the fitting 702 is removably attached to the adapter 704.

In still further examples, at least part of the adapter may be rotatablerelative to the cuff 12. In some examples, such rotation may be about arotational axis that extends substantially perpendicular to the topsurface 54 of the cuff. Additionally or alternatively, such rotation maybe about a rotational axis that extends substantially parallel to thetop surface 54 of the cuff. For example, as shown in FIGS. 8 a and 8 b ,an example system 800 or other environment of the present disclosure mayinclude a fitting 802 that is configured to be removably attached to ablood pressure cuff adapter 804 by movement of the fitting 802 in afirst direction substantially parallel to the top surface 54 of the cuff12. In such examples, the fitting 802 may also be configured to bedetached from the adapter 804 by moving the fitting 802 in a seconddirection substantially parallel to the top surface 54 of the cuffopposite the first direction. As will be described below, such anadapter 804 may include one or more hinges configured to facilitaterotation of at least part of the adapter 804, relative to the cuff 12,while the fitting is removably attached to the adapter 804. In exampleembodiments, any of the structures, functions, and/or other aspects ofthe various fittings described herein may be included in the fitting802. Likewise, any of the structures, functions, and/or other aspects ofthe various adapters described herein may be included in the adapter804. Further, one or more of the structures, functions, and/or featuresof the fitting 802, and/or of the adapter 804, may be incorporated intoany of the fittings or adapters of the present disclosure.

In the example system 800, various components of the fitting 802 may besubstantially similar to corresponding components of, for example, thefitting 602, and various components of the adapter 804 may besubstantially similar to corresponding components of, for example, theadapter 604. For example, the fitting 802 may include a substantiallyrigid body 806, and one or more arms 808 a, 808 b extending from thebody 806. The first and second arms 808 a, 808 b may also includerespective shelves 810 a, 810 b formed at respective distal ends of thearms 808 a, 808 b. In the embodiment of FIGS. 8 a and 8 b , the arms 808a, 808 b may be movably connected to the body 806 via a directconnection with the body 806 and/or via one or more posts (not shown) orother pieces of material extending substantially laterally from the body806 to the respective arms 808 a, 808 b. As can be seen from at leastFIG. 8 a , the first and second shelves 810 a, 810 b may extendsubstantially perpendicularly from the respective arms 808 a, 808 b. Inparticular, such first and second shelves 810 a, 810 b may include oneor more surfaces (e.g., a top surface, a bottom surface opposite the topsurface, a side surface, etc.), extending substantially perpendicularlyfrom the respective arms 808 a, 808 b, and such surfaces may beconfigured to mate with a corresponding surface of the adapter 804 inorder to removably attach the fitting 802 to the adapter 804.

At least one of the body 806, arms 808 a, 808 b, shelves 810 a, 810 b,and/or other components of the fitting 802 may be made from any of thematerials described above with respect to the body 48. In any suchexamples, the arms 808 a, 808 b and/or shelves 810 a, 810 b may bemoveable relative to the body 806 when force is applied to respectivegrips 814 a, 814 b associated with the arms 808 a, 808 b. For example, ahealthcare practitioner may apply an inward force (e.g., in a directiontoward the body 806 of the fitting 802) to one or both of the grips 814a, 814 b. The application such an inward force to the grip 814 a maycause the arm 808 a to pivot relative to, for example, a first sidewallof the fitting 802, thereby causing the shelf 810 a to move laterallyaway from the body 806 and/or a central longitudinal axis of the fitting802. Likewise, the application such an inward force to the grip 814 bmay cause the arm 608 b to pivot relative to, for example, a secondsidewall of the fitting 802 opposite the first sidewall, thereby causingthe shelf 810 b to move laterally away from the body 806 and/or acentral longitudinal axis of the fitting 802. Such movement of theshelves 810 a, 810 b may enable the fitting 802 to be removably attachedto the blood pressure cuff adapter 804 when the fitting 802 is moved ina first direction of arrow 842 substantially parallel to the top surface54 of the cuff 12. Similarly, such movement of the shelves 810 a, 810 bmay enable the fitting 802 to be detached from the adapter 804 when thefitting 802 is moved in a second direction of arrow 844 opposite thefirst direction and substantially parallel to the top surface 54 of thecuff 12.

The fitting 802 may also include one or more extensions, passages,and/or other like channels 816 extending from the body 806. In someexamples, the channel 816 may extend substantially along thelongitudinal axis of the fitting 802, and the longitudinal axis mayextend substantially centrally through the channel 816. The channel 816may form an opening 818 configured to permit the passage of air or otherfluids into the cuff 12 via the fitting 802, and/or to otherwise fluidlyconnect the fitting 802 with the cuff 12, when the fitting 802 isremovably attached to the adapter 804. The fitting 802 may furtherinclude a central fluid passage 819 extending at least partially throughthe body 806. For example, the channel 816 may form at least part of thecentral fluid passage 819 of the fitting 802, and the longitudinal axisof the fitting 802 may extend substantially centrally through at leastpart of the central passage 819. In such examples, the opening 818 ofthe channel 816 may comprise an opening of the central passage 819.

As noted above with respect to the adapter 50 of FIG. 2 , the adapter804 may include a substantially rigid body 820 that is at least partlyconnected to the cuff 12. For example, the body 820 may include a distalportion 821 extending outwardly from the outer surface 54 of the cuff12. The body 820 may also include a proximal portion 836 embedded withinthe cuff 12 and/or extending inwardly from the outer surface 54. In someexamples, a top surface of the proximal portion 836 may extend at leastpartly along and/or may be connected to an inner surface of the cuff 12disposed opposite the outer surface 54. As shown in FIG. 8 b , the body820 may include a hinge 825 rotatably connecting the distal portion 821to the proximal portion 836. In particular, the hinge 825 may enable thedistal portion 821 to be rotated about a rotational axis R of the hinge825 and relative to the proximal portion 836. In such examples, thedistal portion 821 may include a central longitudinal axis X and theproximal portion 836 may include a central longitudinal axis Y extendingsubstantially perpendicular to, and coplanar with, the longitudinal axisX. In such examples, the rotational axis R may extend substantiallyperpendicular to the plane in which the axes X and Y are disposed. Forexample the hinge 825 may enable the distal portion 821 to rotate, aboutthe rotational axis R, in the clockwise direction of arrow 838 and inthe counterclockwise direction of arrow 840.

In any of the examples described herein, the longitudinal axis X mayextend substantially centrally through a section of the distal portion821 formed, at least in part, by first, second, third, and fourth walls846, 848, 850, 852 of the distal portion 821. For example, the firstwall 846 may extend substantially parallel to the second wall 848, andthe third wall 850 may extend substantially parallel to the fourth wall852. Together, the first, second, third, and fourth walls 846, 848, 850,852 may define at least part of a first central fluid passage 831 of thedistal portion 821. The proximal portion 836 may also include one ormore walls similar to the first, second, third, and fourth walls 846,848, 850, 852 (e.g., a substantially cylindrical wall 854), and thelongitudinal axis Y may extend substantially centrally through a sectionof the proximal portion 836 formed, at least in part, by the one or morewalls of the proximal portion 836. For example, the one or more walls ofthe proximal portion 836 may define at least part of a central fluidpassage 830 of the proximal portion 836. In such examples, the fluidpassage 831 of the distal portion 821 may be fluidly connected to thefluid passage 830 of the proximal portion 836 via, for example, acentral fluid passage 829 of the hinge 225. In such examples, the firstlongitudinal axis X may extend substantially parallel to the top surface54 of the cuff 12, and may extend substantially centrally through thecentral passage 831. Additionally, the longitudinal axis Y may extendsubstantially perpendicular to the top surface 54 of the cuff 12, andmay extend substantially centrally through the central passage 830.

The body 820 of the adapter 804 may be made from any of the materialsdescribed above with respect to, for example, the fitting 42. In someexamples, the adapter 804 may be made from more than one such material.For example, one or more components or other parts of the distal portion821 may be made from a first material, and one or more components orother parts of the proximal portion 836 may be made from a secondmaterial different from the first material. As noted above with respectto the adapter 50 of FIG. 2 , in such examples, the use of such firstand second materials may result in the various components or other partsof the body 820 having different rigidities, durabilities, sealingcharacteristics, and/or other properties.

The distal portion 821 of the adapter 804 may include a ring 822disposed at an open end of the distal portion 821. In such examples, thering 822 may form an opening 823 of the central passage 831, and thering 822 may be formed, at least in part, by distal ends of the first,second, third, and fourth walls 846, 848, 850, 852. The ring 822, andthe opening 823 formed thereby, may be shaped, sized, and/or otherwiseconfigured to allow at least part of the channel 816 to passtherethrough when the fitting 802 is removably attached to the adapter804. In such examples, the channel 816 may pass through the ring 822and/or the opening 823, and at least part of the channel 816 may bedisposed within the central passage 831 of the adapter 804 when thefitting 802 is removably attached to the adapter 804. In such examples,the system 800 may also include one or more O-rings, gaskets, and/orother seals 828 configured to form a substantially fluid-tight sealbetween the fitting 802 and the adapter 804 when the fitting 802 isremovably attached to the adapter 804. For example, at least one seal828 may be attached to, adhered to, embedded substantially within,and/or otherwise connected to either an outer surface 834 of the fitting802 or to a corresponding distal and/or other outer surface of the ring822 to facilitate forming such a fluid-tight seal. In the example system800, the seal 828 may be connected to the ring 828, and the seal 628 mayengage the outer surface 834 of the fitting 802 proximate a perimeterand/or outer wall of the channel 816 to form a substantially fluid-tightseal with the fitting 802 when the fitting 802 is removably attached tothe adapter 804. Alternatively, the seal 828 may be attached to, adheredto, embedded substantially within, and/or otherwise connected to theouter surface 834 of the fitting 802, and may be configured to engagethe distal and/or other outer surface of the ring 822 to form such asubstantially fluid-tight seal.

The body 820 of the adapter 804 may also include a first ridge 824 aformed on an inner surface 826 of the wall 852, and within the centralpassage 831. The body 820 may also include a second ridge 824 b formedon an inner surface of the wall 850 opposite the inner surface 826, andwithin the central passage 831. The first ridge 824 a may be configuredto mate with the first shelf 810 a of the fitting 802, when the arm 808a and/or the first shelf 810 a are disposed at least partly within thecentral passage 831, to assist in retaining the fitting 802 and/orotherwise removably attaching the fitting 802 to the adapter 804.Likewise, the second ridge 824 b may be configured to mate with thesecond shelf 810 b of the fitting 802, when the arm 808 b and/or thesecond shelf 810 b are disposed at least partly within the centralpassage 831, to assist in retaining the fitting 802 and/or otherwiseremovably attaching the fitting 802 to the adapter 804. In someexamples, at least part of the first ridge 824 a may extendsubstantially perpendicular to the inner surface 826 of the wall 852,and at least part of the second ridge 824 b may extend substantiallyperpendicular to the inner surface of the wall 850 opposite the innersurface 826. As shown in FIG. 8 a , at least one of the ridges 824 a,824 b may include corresponding camming surfaces extending at an angle(e.g., an acute angle) from the inner surfaces of the walls 850, 852 toends of the respective ridges 824 a, 824 b. Such camming surfaces may beshaped, sized, located, and/or otherwise configured such that at leastpart of the arms 808 a, 808 b and/or other components of the fitting 802may slide along the camming surfaces as the fitting 802 is removablyattached to the adapter 804. For example, in other embodiments suchcamming surfaces may be substantially convex, substantially concave,substantially curved, substantially tapered, and/or any otherconfiguration in order to assist in removably attaching the fitting 802to the adapter 804.

FIG. 9 illustrates still another example system 900 of the presentdisclosure including a fitting 902 configured to facilitate transmissionof pressurized air or other fluids to an adapter 920 fluidly connectedto a blood pressure cuff 12. The fitting 902 may include a distal end904 configured to mate with the adapter 920, and a proximal end 906opposite the distal end 904. The distal end 904 may include one or moreshafts 908, 910 configured to be inserted, at least in part, intocorresponding openings formed by a distal end 922 of the adapter 920.For example, the first shaft 908 may comprise a barb-like connector orany other such fluid connector extending from an outer wall 930 of thefitting 902. The first shaft 908 may include a distal opening 911, andthe opening 911 may comprise a distal opening of a central fluid passage912 of the first shaft 908. Similarly, the second shaft 910 may includea distal opening 913, and the opening 913 may comprise a distal openingof a central fluid passage 914 of the second shaft 910. In suchexamples, one or more sections of tubing 916 may be connected to thefitting 902 at the proximal end 906. For example, tubing 916 havingfirst and second separate conduit sections 918 a, 918 b may be fluidlyconnected to the fitting 902 at the proximal end 906. The fitting 902may comprise separate respective fluid passages configured to transferfluid received from the separate conduit sections 918 a, 918 b to thecuff 12 and/or to the adapter 920.

In such examples, the adapter 920 may include a distal end 922 and aproximal end 924 opposite the distal end 922. The fitting 902 may beremovably attached to the adapter 920 by inserting at least part of thedistal end 904 into corresponding opening(s) formed by the distal end922 of the adapter 920. For example, in some embodiments the adapter 920may include a female port or other like opening (not shown) at thedistal end 922 configured to accept and/or otherwise mate with the malefirst shaft 908. Additionally, in such embodiments the adapter 920 mayinclude a male shaft or other like member (not shown) at the distal end922 configured to extend into the opening 913 and/or otherwise mate withthe second shaft 910. In some examples, the outer wall 930 of thefitting 902 may abut a corresponding outer wall of the distal end 922when the fitting 902 is removably attached to the adapter 920. Theadapter 920 may also include a top surface 926 and a bottom surface 928opposite the top surface 926. In such examples, the bottom surface 928may mate with and/or may be otherwise connected to a correspondingsurface of the cuff 12. Further, the adapter 920 may include one or moreconnection devices 932 operable to assist in removably attaching anddetaching the fitting 902 from the adapter 920.

As shown in FIGS. 10 and 10 a, another example system 1000 or otherenvironment may include a fitting 1002 and/or a blood pressure cuffadapter 1004, and in such systems, the example fitting 1002 may includeone or more arms or other connection devices configured to assist inremovably attaching the fitting 1002 to the adapter 1004. Such examplesystems may also include a groove and/or other structure configured tomate with an annular seal, and the interaction between the groove andthe seal may assist in retaining the fitting 1002 removably attached tothe adapter 1004. In example embodiments, any of the structures,functions, and/or other aspects of the various fittings described hereinmay be included in the fitting 1002. Likewise, any of the structures,functions, and/or other aspects of the various adapters described hereinmay be included in the adapter 1004. Further, one or more of thestructures, functions, and/or features of the fitting 1002, and/or ofthe adapter 1004, may be incorporated into any of the fittings oradapters of the present disclosure.

In the example system 1000, the fitting 1002 may include a substantiallyrigid body 1006, and a single arm 1008 extending from the body 1006. Thearm 1008 may also include a shelf 1010 formed at a distal end of the arm1008. The arm 1008 may be movably connected to the body 1006 via atleast one stand 1012 extending from the body 1006. As can be seen fromFIG. 10 , the shelf 1010 may extend substantially perpendicularly fromthe arm 1008. In particular, the shelf 1010 may include one or moresurfaces (e.g., a top surface, a bottom surface opposite the topsurface, a side surface, etc.), extending substantially perpendicularlyfrom the arm 1008, and such surfaces may be configured to mate with acorresponding surface of the adapter 1004 in order to removably attachthe fitting 1002 to the adapter 1004.

At least one of the body 1006, stand 1012, arm 1008, shelf 1010, and/orother components of the fitting 1002 may be made from any of thematerials described above with respect to the body 48. In any suchexamples, the shape, size, materials, and/or other configuration of thestand 1012 may provide for movement of the shelf 1010 relative to thebody 1006 when force is applied to a grip 1014 associated with the stand1012. Such movement may enable the fitting 1002 to be removably attachedto the blood pressure cuff adapter 1004, and may also enable the fitting1002 to be detached from the adapter 1004. As can be understood from thepartial cross-sectional view shown in FIG. 10 a , in further examples,the fitting 1002 may include more than one arm, shelf, stand, grip,and/or other components. For example, the fitting 1002 of FIG. 10 a mayinclude a first arm 1008 a (not shown) and a second arm 1008 b, a firstshelf 1010 a (not shown) and a second shelf 1010 b, a first stand 1012 a(not shown) and a second stand 112 b, a first grip 1014 a (not shown)and a second grip 1014 b, etc. Additionally, as will be described below,the system 1000 may also include a seal, and a groove configured matewith the seal. Disposing the seal at least partially within the groovewhen removably attaching the fitting 1002 to the adapter 1004 may assistin removably attaching the fitting 1002 to the adapter 1004. Disposingthe seal at least partially within the groove when removably attachingthe fitting 1002 to the adapter 1004 may also form a substantiallyfluid-tight seal between the fitting 1002 and the adapter 1004.

The fitting 1002 may also include one or more extensions, passages,and/or other like channels 1016 extending from the body 1006. In someexamples, the channel 1016 may extend substantially along thelongitudinal axis Z (FIG. 2 ) of the fitting 1002, and the longitudinalaxis Z may extend substantially centrally through the channel 1016. Thechannel 1016 may form an opening 1018 configured to permit the passageof air or other fluids into the cuff 12 via the fitting 1002, and/or tootherwise fluidly connect the fitting 1002 with the cuff 12, when thefitting 1002 is removably attached to the adapter 1004. The fitting 1002may further include a central fluid passage 1019 extending at leastpartially through the body 1006. For example, the channel 1016 may format least part of the central fluid passage 1019, and the longitudinalaxis Z (FIG. 2 ) may extend substantially centrally through at leastpart of the central passage 1019. In such examples, the opening 1018 ofthe channel 1016 may comprise an opening of the central passage 1019.

As noted above with respect to the adapter 50 of FIG. 2 , the adapter1004 may include a substantially rigid body 1020 that is at least partlyconnected to the cuff 12. For example, the body 1020 may include adistal portion 1021 extending outwardly from the outer surface 54 of thecuff 12. The body 1020 may also include a proximal portion 1036 embeddedwithin the cuff 12 and/or extending inwardly from the outer surface 54.In some examples, a top surface 1040 of the proximal portion 1036 mayextend at least partly along and/or may be connected to an inner surfaceof the cuff 12 disposed opposite the outer surface 54. The proximalportion 1036 may also include a bottom surface 1042 opposite the topsurface 1040 and disposed substantially within, for example, an inflatedportion of the cuff 12. The body 1020 of the adapter 1004 may be madefrom any of the materials described above with respect to, for example,the fitting 42. In some examples, the adapter 1004 may be made from morethan one such material. For example, one or more components or otherparts of the distal portion 1021 may be made from a first material, andone or more components or other parts of the proximal portion 1036 maybe made from a second material different from the first material. Asnoted above with respect to the adapter 50 of FIG. 2 , in such examples,the use of such first and second materials may result in the variouscomponents or other parts of the body 1020 having different rigidities,durabilities, sealing characteristics, and/or other properties. In anyof the embodiments described herein, including the example embodimentsshown in FIGS. 10 and 10 a, the fitting 1002 may also be made from morethan one material. For example, one or more portions of the body 1006may be made from a first material, and a seal, at least one stand 1012,at least one arm 1008, and/or other component of the fitting 1002 may bemade from a second material different from the first material.

The distal portion 1021 of the adapter 1004 may include an annular ring1022 having a top surface 1026 and a ridge 1024 disposed opposite thetop surface 1026. The ridge 1024 may comprise at least part of a bottomsurface of the ring 1022. In such examples, at least part of the ridge1024 and/or at least another part of the bottom surface of the ring 1022may be configured to mate with the shelf 1010 of the fitting 1002 toassist in retaining the fitting 1002 and/or otherwise removablyattaching the fitting 1002 to the adapter 1004. In some examples, atleast part of the ridge 1024 and/or at least another part of the bottomsurface of the ring 1022 may extend substantially perpendicular to alongitudinal axis X of the body 1020. Additionally, the adapter 1004 mayinclude a substantially cylindrical sidewall 1038 extending from theridge 1024 to the top surface 1040 of the proximal portion 1036. Such asidewall 1038 may space the ridge 1024 from the top surface 1040 suchthat the shelf 1010 of the fitting 1002 may have room to mate with theridge 1024 beneath the ring 1022.

The top surface 1026 of the ring 1022 may be substantially convex,substantially concave, substantially curved, substantially tapered,and/or any other configuration in order to assist in removably attachingthe fitting 1002 to the adapter 1004. In some examples, the top surface1026 of the ring 1022 may comprise a convex surface extending radiallyaway from the longitudinal axis X of the body 1020 from a distal end1030 of the top surface 1026 to a proximal end 1032 of the top surface1026. In such examples, the curved top surface 1026 may comprise acamming surface along which at least part of the arm 1008 and/or othercomponents of the fitting 1002 may slide as the fitting 1002 isremovably attached to the adapter 1004.

The system 1000 may also include one or more O-rings, gaskets, and/orother seals 1028 configured to form a substantially fluid-tight sealbetween the fitting 1002 and the adapter 1004 when the fitting 1002 isremovably attached to the adapter 1004. For example, at least one seal1028 may be attached to, adhered to, embedded substantially within,formed integrally with, and/or otherwise connected to either an outersurface 1034 of the fitting 1002 or to one or more portions of anannular groove 1043 formed by the ring 1026 to facilitate forming such afluid-tight seal. As shown in FIG. 10 , the seal 1028 may be connectedto a portion of the outer surface 1034, and in some examples, at leastpart of the seal 1028 may be recessed and/or otherwise disposed in agroove formed by the outer surface and substantially surrounding thechannel 1016. Alternatively, as shown in FIG. 10 a , the seal 1028 maybe embedded within and/or formed integrally with the body 1006 of thefitting 1002. In such examples, the seal 1028 may comprise a portion ofthe body 1006 configured to mate with the groove 1043 so as to form asubstantially fluid-tight seal with the groove 1043 and/or otherportions of the adapter 1004 (e.g., with the ring 1022) when the fitting1002 is removably attached to the adapter 1004. In such examples, theseal 1028 may be formed from a first material (e.g., a first urethaneand/or other polymer having a relatively low durometer), and at leastpart of the body 1006 may be formed from a second material (e.g., asecond urethane and/or other polymer having a durometer higher than thefirst material) different from the first material.

In further example embodiments, the body 1006 shown in FIG. 10 a may beformed from a single material. In such examples, at least the ring 1022of the adapter 1004 may be formed from a first material (e.g., a firsturethane and/or other polymer having a relatively low durometer), andthe body 1006 may be formed from a second material (e.g., a secondurethane and/or other polymer having a durometer higher than the firstmaterial) different from the first material. In such examples, a portionof the body 1006 may be configured to mate with the groove 1043 so as toform a substantially fluid-tight seal with the groove 1043 and/or otherportions of the adapter 1004 (e.g., with the ring 1022) when the fitting1002 is removably attached to the adapter 1004.

In the example system 1000 of FIGS. 10 and 10 a, the groove 1043 may beformed, at least in part, by the top surface 1026 of the ring 1022, andthe groove 1043 may comprise a base 1046 extending substantiallyperpendicular to the longitudinal axis X, and a sidewall 1048 extendingsubstantially parallel to the longitudinal axis X. In such examples, thesidewall 1048 may extend distally from the base 1046 to the distal end1030 of the top surface 1026.

Further, as shown in at least FIG. 10 the adapter 1004 may include asubstantially cylindrical inner wall 1044 having a proximal end 1052 atthe bottom surface 1042 of the proximal portion 1036, and a distal end1050 at the base 1046 of the groove 1043. In such examples, the base1046 may extend radially from the distal end 1050 of the inner wall 1044to the sidewall 1048. In such examples, at least part (e.g., a base1056) of the seal 1028 may be disposed within the groove 1043 when thefitting 1002 is removably attached to the adapter 1004. For example, inembodiments in which the seal 1028 is connected to the fitting 1002(e.g., the embodiment of FIG. 10 ) or in which the seal 1028 is formedintegrally with the fitting 1002 (FIG. 10 a ), the base 1056 of the seal1028 may mate with and/or otherwise contact at least part of the base1046 when the fitting 1002 is removably attached to the adapter 1004.Similarly, in such embodiments a radially outermost sidewall 1058 of theseal 1028 may mate with and/or otherwise contact at least part of thesidewall 1048 when the fitting 1002 is removably attached to the adapter1004. Alternatively, in embodiments in which the seal 1028 is formedintegrally with and/or connected to the adapter 1004, the base 1056 ofthe seal 1028 may be connected to the base 1046 of the groove 1043.Further, in such embodiments at least part of the radially outermostsidewall 1058 of the seal 1028 may be connected to the sidewall 1048 ofthe groove 1043. In such examples, the seal 1028 may engage the outersurface 1034 of the fitting 1002 and/or an outer surface 1054 of thechannel 1016 to form a substantially fluid-tight seal with the fitting1002. Such engagement may also assist in removably attaching the fitting1002 to the adapter 1004. For example, the flexible seal 1028 may havean inner diameter that is substantially equal to or nominally less thanan outer diameter of the outer surface 1054. Accordingly, the seal 1028may apply a retention force to the outer surface 1054 in a radiallyinward direction when the channel 1016 is inserted within the adapter1004. Such a retention force may assist in removably attaching thefitting 1002 to the adapter 1004.

In still further examples, in the embodiment shown in FIG. 10 , the seal1028 may be attached to, adhered to, embedded substantially within,and/or otherwise connected to the outer surface 1034 of the fitting 1002(as described above) and/or to the outer surface 1054 of the channel1016. For example, as noted above with respect to FIG. 10 a top portionof the seal 1028 may be connected to a groove formed by the outersurface 1034 of the fitting 1002. Further, at least part of a sidewallof the seal 1028 (e.g., a radially inner sidewall of the seal 1028 shownin FIG. 10 ) may be connected to and/or disposed on the outer surface1054 of the channel 1016. In such examples, the seal 1028 may engage thesidewall 1048 and/or the base 1046 of the groove 1043 formed by theadapter 1004 to form a substantially fluid-tight seal with the adapter1004. Such engagement may also assist in removably attaching the fitting1002 to the adapter 1004. For example, the flexible seal 1028 may havean outer diameter that is substantially equal to or nominally greaterthan a diameter of the groove 1043 formed by the sidewall 1048.Accordingly, the seal 1028 may apply a retention force to the sidewall1048 in a radially outward direction when the channel 1016 is insertedwithin the adapter 1004. Such a retention force may assist in removablyattaching the fitting 1002 to the adapter 1004. In the embodiment shownin FIG. 10 , the seal 1028 may comprise a primary seal configured tomate with at least a portion of the fitting 1002 (e.g., the outersurface 1034), and the annular ring 1022 may comprise a secondary sealthat is also configured to mate with at least a portion of the fitting1002 (e.g., the outer surface 1054 of the channel 1016 and/or the outersurface 1034. In such examples, the seal 1028 and/or the ring 1022 maybe shaped, sized, located, and/or otherwise configured to increase thestability of the removable connection between the adapter 1004 and thefitting 1002.

Further, the body 1020 of the adapter 1004 may also include a centralopening (as shown more clearly in FIG. 2 ) at least partially formed bythe wall 1044 of the body 1020. For example, the inner wall 1044 maydefine a central fluid passage of the adapter 1004 configured to acceptair or other fluids delivered to the cuff 12 via the fitting 1002. Insuch examples, the inner wall 1044 may have any shape, size, diameter,and/or other configuration such that the inner wall 1044 may accept atleast part of the channel 1016 therein. For example, at least part ofthe channel 1016 may pass through the central opening of the inner wall1044, proximate the distal end 1030 of the top surface 1026, when thefitting 1002 is removably attached to the adapter 1004. In suchexamples, the longitudinal axis X may extend substantially centrallythrough the central fluid passage of the adapter 1004 formed by thesubstantially cylindrical inner wall 1044.

As shown in FIG. 11 , still another example system 1100 or otherenvironment may include a fitting 1102 and/or a blood pressure cuffadapter 1104, and in such systems, the example fitting 1102 may beconfigured to mate with the adapter 1104 by moving the fitting 1102 in adirection substantially perpendicular to a central longitudinal axis Xof the adapter 1104 and/or in a direction substantially parallel to atop surface of the cuff 12 to which the adapter 1104 is connected. Suchexample fittings 1102 may include a groove and/or other structureconfigured to assist in securing the fitting 1102 to the adapter 1104when the fitting 1102 is removably attached to the adapter 1104. Inexample embodiments, any of the structures, functions, and/or otheraspects of the various fittings described herein may be included in thefitting 1102. Likewise, any of the structures, functions, and/or otheraspects of the various adapters described herein may be included in theadapter 1104. Further, one or more of the structures, functions, and/orfeatures of the fitting 1102, and/or of the adapter 1104, may beincorporated into any of the fittings or adapters of the presentdisclosure.

In the example system 1100, the fitting 1102 may include a substantiallyrigid body 1106, and the body 1106 may be substantially cylindricaland/or any other shape configured to assist in mating the fifing 1102with the adapter 1104. The body 1106 may include, for example, a pocket1108 shaped, sized, and/or otherwise configured to accept at least partof the adapter 1104 therein and to form a substantially fluid-tight sealwith the adapter 1104. As shown in FIG. 11 , the pocket 1108 may beformed, at least in part, by an inner sidewall 1110 of the body 1106.The pocket 1108 may also be formed, at least in part, by a ceiling 1112of the body 1106 extending substantially perpendicular to the innersidewall 1110. In such examples, the pocket 1108 may include an openingat a distal end of the body 1106 configured to accept at least part ofthe adapter 1104 when the fitting 1102 is removably attached to theadapter 1104. In particular, the opening of the pocket 1108 may enablethe fitting 1102 to be mated with the adapter 1104 by moving the fitting1102 in a direction substantially perpendicular to the centrallongitudinal axis X of the adapter 1104 and/or in a directionsubstantially parallel to a top surface of the cuff 12 to which theadapter 1104 is connected. The body 1106 may also include an outer topsurface 1114 opposite the ceiling 1112, and an inner bottom surface 1116opposite the top surface 1114. In such examples, the bottom surface 1116may be disposed proximate and/or adjacent to the top surface of the cuff12 when the fitting 1102 is removably attached to the adapter 1104.

In some examples, the body 1106 may also include a substantiallycircumferential groove 1118. For example, the groove 1118 may comprise achannel or other like structure formed by the inner sidewall 1110 andextending at least partially circumferentially around a centrallongitudinal axis (not shown) of the fitting 1102. The groove 1118 mayinclude any width, height, depth, and/or other configuration/structureto assist in removably attaching the fitting 1102 with the adapter 1104.For example, as will be described below, the adapter 1104 may include adistal portion having a ring and a ridge, and in such embodiments thegroove 1118 may be configured to accept at least part of the distalportion therein when the fitting 1102 is removably attached to theadapter 1104. Further, while the opening of the pocket 1108 may enablethe fitting 1102 to be mated with the adapter 1104 by moving the fitting1102 in a direction substantially perpendicular to the centrallongitudinal axis X of the adapter 1104 and/or in a directionsubstantially parallel to a top surface of the cuff 12, the groove 1118may be substantially annular and/or any other configuration so as toenable rotation of the fitting 1102 about the longitudinal axis X whenthe fitting 1102 is removably attached to the adapter 1104.

As shown in FIG. 11 , the adapter 1104 may include a substantially rigidbody 1120 that is at least partly connected to the cuff 12. For example,the body 1120 may include a distal portion 1121 extending outwardly fromthe outer surface of the cuff 12. The body 1120 may also include aproximal portion 1136 embedded within the cuff 12 and/or extendinginwardly from the outer surface of the cuff 12. In some examples, a topsurface of the proximal portion 1136 may extend at least partly alongand/or may be connected to an inner surface of the cuff 12. The body1120 of the adapter 1104 may be made from any of the materials describedabove with respect to, for example, the fitting 42. In some examples,the adapter 1104 may be made from more than one such material. Forexample, one or more components or other parts of the distal portion1121 may be made from a first material, and one or more components orother parts of the proximal portion 1136 may be made from a secondmaterial different from the first material.

The distal portion 1121 of the adapter 1104 may include an annular ring1122 having a top surface 1126 and a ridge 1124 disposed opposite thetop surface 1126. The ridge 1124 may comprise at least part of a bottomsurface of the ring 1122. In such examples, at least part of the ridge1124 and/or at least another part of the bottom surface of the ring 1122may be configured to mate with the groove 1118 of the fitting 1102(e.g., a bottom surface, bottom wall, bottom flange, bottom shelf, etc.)to assist in retaining the fitting 1102 and/or otherwise removablyattaching the fitting 1102 to the adapter 1104. In some examples, atleast part of the ridge 1124 and/or at least another part of the bottomsurface of the ring 1122 may extend substantially perpendicular to thelongitudinal axis X of the body 1120. Further, at least part of theridge 1124 and/or at least part of the ring 1122 may be disposedsubstantially within the groove 1118 when the fitting 1102 is removablyattached to the adapter 1104. Additionally, the adapter 1104 may includea substantially cylindrical sidewall 1138 extending from the ridge 1124to the top surface of the proximal portion 1136. Such a sidewall 1138may space the ridge 1124 from the top surface of the proximal portion1136 such that the groove 1118 of the fitting 1102 may have room to matewith the ridge 1124. In such examples, at least part of the body 1106(e.g., the bottom surface 1116) may be disposed beneath the ring 1122when the fitting 1102 is removably attached to the adapter 1104.

The top surface 1126 of the ring 1122 may be substantially convex,substantially concave, substantially curved, substantially tapered,and/or any other configuration in order to assist in removably attachingthe fitting 1102 to the adapter 1104. In some examples, the top surface1126 of the ring 1122 may comprise a convex surface extending radiallyaway from the longitudinal axis X of the body 1120 from a distal end ofthe top surface 1126 to a proximal end of the top surface 1126.

The system 1100 may also include one or more O-rings, gaskets, and/orother seals 1128 configured to form a substantially fluid-tight sealbetween the fitting 1102 and the adapter 1104 when the fitting 1102 isremovably attached to the adapter 1104. For example, at least one seal1128 may be attached to, adhered to, embedded substantially within,formed integrally with, and/or otherwise connected to either an outersurface of the fitting 1102 or to one or more portions of an annulargroove 1146 formed by the ring 1126 to facilitate forming such afluid-tight seal. In the example system 1100 of FIG. 11 , the groove1146 may be formed, at least in part, by the top surface 1126 of thering 1122. In still further embodiments, the seal 1128 may be omitted.In such example embodiments the adapter 1104 (e.g., at least part of thetop surface 1126 and/or other portions of the ring 1122) may be madefrom a first material (e.g., an example urethane or other polymer)having a first durometer. The fitting 1102, on the other hand, may bemade from a second material (e.g., an example polymer) having a seconddurometer that is relatively higher than the first durometer of thefirst material. In such examples, the relatively lower durometer firstmaterial of the adapter 1104 may be configured to form a substantiallyfluid tight seal with the relatively higher durometer second materialwhen the fitting 1102 is releasable connected to the adapter 1104. Instill further embodiments, the fitting 1102 may be made from therelatively lower durometer first material described above and theadapter 1104 may be made from the relatively higher durometer secondmaterial described above.

Further, in any of the embodiments of the system 1100 shown in FIG. 11 ,the fitting 1102 may be shaped, sized, and/or otherwise configured to beinstalled directly over the top of the adapter 1104 in order to form aremovable connection therewith and/or to form a substantiallyfluid-tight seal therewith. In such examples, the fitting 1102 (e.g.,the body 1106 of the fitting 1102) may be substantially cylindrical, andmay be configured to form a substantially fluid-tight seal with the seal1128 and/or with at least part of the ring 1122 when the fitting 1102 isremovably connected to the adapter 1104.

Further, as shown in FIG. 11 the adapter 1104 may include asubstantially cylindrical inner wall 1144 having a proximal end at abottom surface of the proximal portion 1036, and a distal end at the topsurface 1126 of the ring 1122. In such examples, the inner wall 1144 mayform a central opening 1160 of the adapter 1104 extending from thebottom surface of the proximal portion 1036 to the top surface 1126 ofthe ring 1122. In such examples, the longitudinal axis X may extendsubstantially centrally through the central opening 1160 formed by theinner wall 1114.

In example embodiments, the body 1106 may also include one or morechannels 1150 a, 1150 b. For example, such channels 1150 a, 1150 b maybe formed, at least in part, by the ceiling 1112 and may extend into theceiling 1112 at any desired depth. Each channel 1150 a, 1150 b may befluidly connected to a respective fluid passage 1152 a, 1152 b of thebody. For example, each fluid passage 1152 a, 1152 b may be fluidlyconnected to a respective conduit section 32 a, 32 b of the tubing 30.As a result, fluid delivered to the body 1106 by the conduit sections 32a, 32 b may be passed to the channels 1150 a, 1150 b by the respectivefluid passages 1152 a, 1152 b, and the channels 1150 a, 1150 b may passsuch fluid to the central opening 1160 of the adapter 1104 when thefitting 1102 is removably attached to the adapter 1104.

As shown in FIG. 12 , yet another example system 1200 or otherenvironment may include a fitting 1202 and/or a blood pressure cuffadapter 1104, and in such systems, the example fitting 1102 may beconfigured to mate with the adapter 1104 by moving the fitting 1102 in adirection substantially perpendicular to a rotational axis R defined bythe adapter 1204. In some examples, the rotational axis R may comprise acentral longitudinal axis of the adapter 1104, and the fitting 1202 maybe configured to rotate about the rotational axis R when the fitting1202 is removably attached to the adapter 1204. As shown in FIG. 12 ,the rotational axis R may extend substantially parallel to a top surface54 of the cuff 12 to which the adapter 1204 is connected, and thefitting 1202 may have a range of motion about the rotational axis Requal to at least approximately 180 degrees. For example, the fitting1202 may be rotatable about the rotational axis R in the clockwisedirection of arrow 1210 and in the counterclockwise direction of arrow1212. It is understood that such an example adapter 1204 may have one ormore grooves, channels, pockets, and/or other structures configured tomate with at least part of the fitting 1202, and such structures mayassist in removably attaching the fitting 1202 to the adapter 1204.

The adapter 1204 and/or the fitting 1202 mayalso include one or more seals (not shown) similar to one or more of theseals described above, to assist in forming such a substantiallyfluid-tight seal.

In some examples, the adapter 1204 may include a first portion 1208 aand a second portion 1208 b disposed opposite the first portion 1208 aon the top surface 54. In such examples, the body 1206 of the fitting1202 may be positioned between the first and second portions 1208 a,1208 b when the fitting 1202 is removably attached to the adapter 1204.Further, the first and second portions 1208 a, 1208 b may includerespective fluid passages configured to direct fluid into the cuff 12.In such examples, a first fluid passage of the fitting 1202 may befluidly connected to a respective fluid passage of the first portion1208 a, and a second fluid passage of the fitting 1202 may be fluidlyconnected to a respective fluid passage of the second portion 1208 bwhen the fitting 1202 is removably attached to the adapter 1204.

In the example system 1300, various components of the fitting 1302 maybe substantially similar to corresponding components of the fitting 502,and various components of the adapter 1304 may be substantially similarto corresponding components of the adapter 504. The body 1306 and/orother components of the fitting 1302 may be made from any of thematerials described above with respect to the body 48. In any suchexamples, the shape, size, materials, and/or other configuration of theupper portion 1308 may enable at least one of the first portion 1310 a,or the second portion 1310 b to mate with a surface of the adapter 1304.Such flexibility and/or malleability of the upper section 1308 mayenable the fitting 1302 to be removably attached to the blood pressurecuff adapter 1304.

The fitting 1302 may also include one or more extensions, passages,and/or other like channels 1316 extending from the body 1306. In someexamples, the channel 1316 may extend substantially along thelongitudinal axis X of the fitting 1302, and the longitudinal axis X mayextend substantially centrally through the channel 1316. The channel1316 may form an opening 1318 configured to permit the passage of air orother fluids into the cuff 12 via the fitting 1302, and/or to otherwisefluidly connect the fitting 1302 with the cuff 12, when the fitting 1302is removably attached to the adapter 1304. The fitting 1302 may furtherinclude a central fluid passage 1319 extending at least partiallythrough the body 1306. For example, the channel 1316 may form at leastpart of the central fluid passage 1319 of the fitting 1302, and thelongitudinal axis X may extend substantially centrally through at leastpart of the central passage 1319. In such examples, the opening 1318 ofthe channel 1316 may comprise an opening of the central passage 1319.

The ridge 1324 maycomprise at least part of a bottom surface of the ring 1322. In suchexamples, at least part of the ridge 1324 and/or at least another partof the bottom surface of the ring 1322 may be configured to mate with atleast one of the first portion 1310 a or the second portion 1310 b ofthe fitting 1302 to assist in retaining the fitting 1302 and/orotherwise removably attaching the fitting 1302 to the adapter 1304. Insome examples, at least part of the ridge 1324 and/or at least anotherpart of the bottom surface of the ring 1322 may extend substantiallyperpendicular to the longitudinal axis X. Additionally, the adapter 1304may include a substantially cylindrical sidewall extending proximallyfrom the ridge. Such a sidewall may space the ridge 1324 from a proximalportion of the adapter 1304 such that a healthcare professional may moldand/or otherwise form at least one of the first portion 1310 a or thesecond portion 1310 b of the fitting 1302 to mate with the ridge 1324beneath the ring 1322.

The system 1300 may also include one or more O-rings, gaskets, and/orother seals 1328 configured to form a substantially fluid-tight sealbetween the fitting 1302 and the adapter 1304 when the fitting 1302 isremovably attached to the adapter 1304. For example, at least one seal1328 may be attached to, adhered to, embedded substantially within,and/or otherwise connected to either an outer surface 1334 of thefitting 1302 or to the top surface 1326 of the ring 1322 to facilitateforming such a fluid-tight seal. In the example system 1300, at leastpart (e.g., a base) of the seal 1328 may be disposed within an annulargroove formed by the top surface 1326 of the ring 1322. In suchexamples, the seal 1328 may engage the outer surface 1334 of the fitting1302 proximate a perimeter and/or outer wall of the channel 1316 to forma substantially fluid-tight seal with the fitting 1302 when the fitting1302 is removably attached to the adapter 1304. Alternatively, the seal13528 may be attached to, adhered to, embedded substantially within,and/or otherwise connected to the outer surface 1334 of the fitting1302, and may be configured to engage the top surface 1326 of theadapter 1304 to form such a substantially fluid-tight seal.

For example, the arms 1408a, 1408 b may include respective shelfs 1410 a, 1410 b formed atrespective distal ends of the arms 1408 a, 1408 b. The arms 1408 a, 1408b may be movably connected to the body 1406 via respective stands 1412a, 1412 b extending from the body 1406. As can be seen from FIGS. 14a-14 f , the shelves 1410 a, 1410 b may extend substantiallyperpendicularly relative to the longitudinal axis X. In particular, therespective shelves 1410 a, 1410 b may include one or more surfaces(e.g., a top surface, a bottom surface opposite the top surface, a sidesurface, etc.), extending substantially perpendicularly relative to acentral longitudinal axis X of the adapter 1410, and such surfaces maybe configured to mate with respective corresponding surfaces of theadapter 1404 in order to removably attach the fitting 1402 to theadapter 1404 as described above.

Additionally, the system 1400 may include one or more O-rings, gaskets,and/or other seals 1437 configured to form a substantially fluid-tightseal between the fitting 1402 and the adapter 1404 when the fitting 1402is removably attached to the adapter 1404. Such seals 1437 may besubstantially similar to and/or the same as the one or more seals 737described above with respect to, for example, FIGS. 7 a-7 g . Forexample, the fitting 1402 may include a central channel 1416 defining acentral fluid passage of the fitting 1402, and when the fitting 1402 isremovably attached to the adapter 1404, a substantially cylindricalouter wall 1440 of the fitting 1402 disposed opposite the channel 1416may be disposed along, adjacent, and/or at least partly in contact witha corresponding substantially cylindrical inner wall 1438 of the adapter1404. In such examples, the at least one seal 1437 may be attached to,adhered to, embedded substantially within, disposed adjacent to, and/orotherwise connected to the inner wall 1438 of the adapter 1404 tofacilitate forming such a fluid-tight seal. In particular, the seal 1437may engage the outer wall 1440 to form a substantially fluid-tight sealwith the fitting 1402 when the fitting 1402 is removably attached to theadapter 1404.

With continued reference to FIGS. 14 a-14 f , and as described abovewith respect to at least the adapter 1404 of FIGS. 7 a-7 g , the adapter1404 of the system 1400 may include a substantially rigid body that isat least partly connected to a cuff 12. For example, the body of theadapter 1404 may include a distal portion 1421 extending outwardly froman outer surface of the cuff 12. The body of the adapter 1404 may alsoinclude a proximal portion embedded within the cuff 12 and/or extendinginwardly from the outer surface of the cuff 12. The distal portion 1421of the adapter 1404 may include an annular ring 1422 having a topsurface 1426 and a ridge 1424 disposed opposite the top surface 1426.The ridge 1424 may comprise at least part of a bottom surface of thering 1422. In such examples, at least part of the ridge 1424 and/or atleast another part of the bottom surface of the ring 1422 may beconfigured to mate with the shelves 1410 a, 1410 b of the fitting 1402to assist in retaining the fitting 1402 and/or otherwise removablyattaching the fitting 1402 to the adapter 1404. In some examples, atleast part of the ridge 1424 and/or at least another part of the bottomsurface of the ring 1422 may extend substantially perpendicular to thelongitudinal axis X of the adapter 1404. Additionally, the adapter 1404may include a substantially cylindrical sidewall extending proximallyfrom the ridge 1424. Such a sidewall may space the ridge 1424 from, forexample, the top surface of the cuff 12 such that the shelves 1410 a,1410 b of the fitting 1402 may have room to mate with the ridge 1424beneath the ring 1422.

With reference to at least FIG. 14 a , in some examples the system 1400may include an adapter 1404 having an annular groove 1428, and a fitting1402 having one or more protruding members 1434 configured to at leastpartly engage the groove 1428 when the fitting 1402 is releasablyattached to the adapter 1404. For example, similar to the adapter 1404described with respect to FIGS. 7 a-7 g , in example embodiments, thering 1422 of the adapter 1404 may include a groove 1428 extending atleast partly (and, in some examples, completely) around (e.g.,concentrically) the longitudinal axis X, and being shaped, sized,located, and/or otherwise configured to accept the member 1434 and/orother structural feature of the adapter 1402. As shown in at least FIG.14 a , such a member 1434 may extend distally (e.g., in a directiontoward the cuff 12 when the fitting 1402 is removably attached to theadapter 1404) from an outer surface 1436 of the fitting 1402 disposedopposite and/or facing the top surface 1426 when the fitting 1402 isremovably attached to the adapter 1404. In some examples, the member1434 may comprise a shaft, pin, rod, tab, rib, ring, ridge, flange,and/or other extension of the body 1406 protruding from the outersurface 1436, and the member 1434 may be useful in laterally and/orotherwise aligning the fitting 1402 with the adapter 1404 when removablyattaching the fitting 1402 to the adapter 1404. In particular, as shownin FIG. 14 a , in some examples the member 1434 may comprise one or moretabs, ribs, rings, ridges, flanges, and/or other structures extendingdistally from the outer surface 1436, and having at least one surfacethat tapers radially inwardly from the outer surface 1436 toward theouter wall 1440. For example, the member 1434 may comprise at least onerib, tab, or other such structure including a radially outermostsidewall 1468. The sidewall 1468 may extend from a proximal end of themember 1434 (e.g., proximate or at the outer surface 1436) to a distalend of the member 1434, and the sidewall 1468 may taper radiallyinwardly from the proximal end of the member 1434 to the distal end ofthe member 1434.

The sidewall 1468 may be substantially planar, substantially concave,substantially convex, and/or any other shape or configuration, and sucha configuration may match a configuration of a corresponding portion ofthe groove 1428. For instance, the member 1434 may also include a base1464 disposed at the distal end thereof, and the groove 1428 may includea base 1452 and a radially outermost sidewall 1454 extending proximallyfrom the base 1452. For example, the sidewall 1454 may extend proximallyfrom the base 1452 to the top surface 1426 of the ring 1422. In suchexamples, the sidewall 1454 may mate with and/or otherwise at leastpartially engage the radially outermost sidewall 1468 of the member 1434when the fitting 1402 is removably attached to the adapter 1404.Similarly, in some examples the base 1452 may mate with and/or otherwiseat least partially engage the base 1464 of the member 1434 when thefitting 1402 is removably attached to the adapter 1404. Such engagementbetween the member 1434 and the groove 1428 may assist in minimizingand/or substantially eliminating lateral movement of the fitting 1402relative to the adapter 1404 when the fitting 1402 is removably attachedto the adapter 1404. In any such examples, the member 1434 may beshaped, sized, dimensioned, located, and/or otherwise configured toprovide additional rigidity, support, and/or stability to the removableconnection between the fitting 1402 and the adapter 1404, while stillfacilitating rotation of the fitting 1402 relative to the adapter 1404.

In such examples, the groove 1428 and the member 1434 may be positionedand/or otherwise configured such that disposing at least part of themember 1434 within the groove 1428 when removably attaching the fitting1402 to the adapter 1404 may cause the longitudinal axis Z of thefitting 1402 (FIG. 2 ) to be collinear with the longitudinal axis X ofthe adapter 1404. Moreover, the sidewall 1468 of the member 1434 and thesidewall 1454 of the groove 1428 may be disposed at complimentary anglesrelative to, for example, the longitudinal axis X to facilitate such amating relationship. For instance, the sidewall 1454 of the groove 1428may be disposed at an acute included angle Θ relative to thelongitudinal axis X. In such examples, the sidewall 1468 of the member1434 may be disposed at a complimentary acute included angle A. Such anexample relationship is shown in FIG. 14 a with respect to an axis 1476extending perpendicular to the longitudinal axis X.

With reference to at least FIG. 14 b , in some examples the system 1400may include an adapter 1404 in which the annular groove 1428 describedabove with respect to FIG. 14 a has been omitted. For example, as shownin FIG. 14 b , an example system 1400 may include a fitting 1402 and anadapter 1404 that are substantially similar to the fitting 1402 andadapter 1404 described above with respect to FIG. 14 a . As shown inFIG. 14 b , however, in some embodiments the top surface 1426 of thering 1422 may terminate at a substantially planar surface (e.g., a base1452). In such examples, the fitting 1402 may also include acorresponding substantially planar base 1456 configured to contact,engage, and/or otherwise mate with the base 1452 when the fitting 1402is removably attached to the adapter 1404. In such examples, the base1456 of the fitting 702 may comprise a substantially planar,substantially annular surface extending radially away from the outersurface 1440. In some examples, the fitting 1402 may also include one ormore additional sidewalls 1458 extending substantially parallel to thesidewall 1440. In any such examples, the base 1456 may extend betweenthe sidewall 1440 and the sidewall 1458. In some examples, the base 1456may extend from the sidewall 1440 to the sidewall 1458. In any suchexamples, the base 1452 of the adapter 704 may comprise a substantiallyplanar annular surface, and the base 1456 may contact, engage, and/orotherwise mate with at least part of the base 1452 when the fitting 1402is removably attached to the adapter 1404.

With reference to at least FIG. 14 c , in some examples the system 1400may include an adapter 1404 having an annular groove 1428, and a fitting1402 having one or more protruding members 1434 configured to at leastpartly engage (e.g., at least partly extend into, at least partlycontact, at least partly slidably engage, etc.) the groove 1428 when thefitting 1402 is releasably attached to the adapter 1404. For example,similar to the adapter 1404 described with respect to FIGS. 7 a-7 g , inexample embodiments, the ring 1422 of the adapter 1404 may include agroove 1428 extending at least partly (and, in some examples,completely) around (e.g., concentrically) the longitudinal axis X, andbeing shaped, sized, located, and/or otherwise configured to accept themember 1434 and/or other structural feature of the adapter 1402. Asshown in at least FIG. 14 c , such a member 1434 may extend distally(e.g., in a direction toward the cuff 12 when the fitting 1402 isremovably attached to the adapter 1404) from an outer surface 1436 ofthe fitting 1402 disposed opposite and/or facing the top surface 1426when the fitting 1402 is removably attached to the adapter 1404. Asdescribed above with respect to FIG. 14 a , in some examples, the member1434 may comprise a shaft, pin, rod, tab, rib, ring, ridge, flange,and/or other extension of the body 1406 protruding from the outersurface 1436, and the engagement between the member 1434 and the groove1428 may assist in laterally and/or otherwise aligning the fitting 1402with the adapter 1404 when removably attaching the fitting 1402 to theadapter 1404. While FIG. 14 c illustrates the groove 1428 and the member1434 being spaced radially from, for example, a radially innermost end1430 of the top surface 1426, in other examples the member 1434, groove1428, ring 1422, and/or other components of the fitting 1402 and/or ofthe adapter 1404 may be disposed and/or configured substantially asdescribed above with respect to FIG. 7 f, 10 a, 14 a , and/or one ormore other embodiments of the present disclosure. For example, in someembodiments the groove 1428 and the member 1434 shown in FIG. 14 c maybe configured substantially the same as the corresponding groove 728 andmember 734 described above with respect to FIG. 7 f.

Moreover, as shown in FIG. 14 c , in addition to the groove 1428, thering 1422 of the adapter 1404 may also include one or more surfaces,sections, and/or other modified portions 1474 configured to acceptand/or otherwise engage with a corresponding additional member 1472 ofthe fitting 1402. In some examples, such a modified portion 1474 of thering 1422 may comprise an additional groove, channel, notch,indentation, hole, or other portion of the ring 1422 that, relative tothe ring 722 and/or the substantially convex top surface 726 shown inFIG. 7 a , has been omitted (e.g., via a molding process) or removed(e.g., via a mechanical or other removal process) from the ring 1422. Insuch examples, the additional groove, channel, notch, indentation, hole,or other modified portion 1474 of the ring 1422 may be substantiallyannular, may extend (at least partially) circumferentially around thelongitudinal axis X, and/or may otherwise be configured similar to thegroove 1428 to facilitate rotation of the fitting 1402 relative to theadapter 1404. Further, in the embodiment of FIG. 14 c the modifiedportion 1474 of the ring 1422 may be formed and/or disposed between thegroove 1428 and the radially innermost end 1430 of the top surface 1426.Additionally or alternatively, the modified portion 1474 of the ring1422 may be formed by and/or disposed on a portion of the ring 1422radially outward of the groove 1428. For example, at least part of themodified portion 1474 may be formed and/or disposed between the groove1428 and a radially outermost end of the top surface 1426.

As shown in FIG. 14 c , in some examples the modified portion 1474 ofthe ring 1422 may comprise a substantially planar portion of the topsurface 1426. Alternatively, in other embodiments the modified portion1474 of the ring 1422 may comprise a substantially curved, substantiallyconcave, and/or substantially convex surface or portion of the ring1422. Further, as shown in FIG. 14 c , in some examples at least aportion 1490 of the top surface 1426 may extend radially inwardly fromthe modified portion 1474, and such a portion 1490 of the top surface1426 may extend substantially perpendicular to the longitudinal axis X.For example, such a portion 1490 of the top surface 1426 may extendradially inward from a first end 1484 (e.g., a radially innermost end)of the modified portion 1474 to a radially outermost sidewall of thegroove 1428 and/or to the radially innermost end 1430 of the top surface1426. Alternatively, as shown in the embodiment of FIG. 14 e , in otherexamples the top surface 1426 may be substantially planar and may extendsubstantially linearly from a radially innermost end 1430 of the topsurface 1426 to a radially outermost end 1432 of the top surface 1426.In the example of FIG. 14 e , the groove 1428 may be spaced radiallyfrom the radially innermost end 1430 by any desired distance. In stillfurther embodiments, the groove 1428 and the member 1434 illustrated inat least FIG. 14 e may be omitted.

In any of the examples described herein, the groove 1428 may include aradially innermost sidewall radially spaced from the radially innermostend 1430 of the top surface 1426 by at least a portion 1488 of the topsurface 1426. In such examples, the substantially planar surface, curvedsurface, and/or other surface of the modified portion 1474 may include afirst end 1484 (e.g., a radially innermost end) disposed at a locationon the top surface 1426 radially spaced from the groove 1428 (e.g.,radially spaced from a radially outermost sidewall of the groove 1428disposed opposite the radially innermost sidewall of the groove 1428).Additionally, in such examples the substantially planar surface, curvedsurface, and/or other surface of the modified portion 1474 may include asecond end 1486 (e.g., a radially outermost end) disposed proximate aradially outermost end of the top surface 1426.

Additionally, in any of the examples described herein the shape, size,location, orientation, and/or other configuration of the modifiedportion 1474 may match a configuration of the additional member 1472 ofthe fitting 1402. For instance, as shown in FIGS. 14 c and 14 e , theadditional member 1472 of the fitting 1402 may comprise a substantiallyplanar portion of the outer surface 1436. Alternatively, in otherembodiments the additional member 1472 may comprise a substantiallycurved, substantially concave, and/or substantially convex surface orportion of the outer surface 1436 opposite and facing the modifiedportion 1474. In such examples, the additional member 1472 may mate withand/or otherwise at least partially engage the modified portion 1474when the fitting 1402 is removably attached to the adapter 1404. Suchengagement between the additional member 1472 and the modified portion1474 may assist in minimizing and/or substantially eliminating lateralmovement of the fitting 1402 relative to the adapter 1404 when thefitting 1402 is removably attached to the adapter 1404. Such engagementmay also provide additional rigidity, support, and/or stability to theremovable connection between the fitting 1402 and the adapter 1404,while still facilitating rotation of the fitting 1402 relative to theadapter 1404. Such engagement may also cause the longitudinal axis Z ofthe fitting 1402 (FIG. 2 ) to be collinear with the longitudinal axis Xof the adapter 1404.

Further, as shown in FIGS. 14 c and 14 e , the additional member 1472and the modified portion 1474 may be disposed at complimentary anglesrelative to, for example, the longitudinal axis X when the fitting 1402is removably attached to the adapter 1404. For instance, the portion ofthe top surface 1426 forming the modified portion 1474 may be disposedat an acute included angle Θ relative to an axis 1478 that extendsparallel to the longitudinal axis X. In such examples, the portion ofthe outer surface 1436 forming the additional member 1472 may bedisposed at a complimentary acute included angle A relative to an axis1476 that extends perpendicular to the axis 1478 and the longitudinalaxis X.

Further, it is understood that in some embodiments the additional member1472 may include and/or comprise one or more pins, flanges, detents,and/or other extensions, and in such embodiments the portion of the topsurface 1426 forming the modified portion 1474 may include one or moregrooves, channels, dimples, indents, and/or other structures configuredto accept such extensions. In still further embodiments, it isunderstood that the groove 1428 may be formed by the fitting 1402 andthe member 1434 may be formed by the adapter 1404.

With reference to at least FIG. 14 d , and substantially similar to theembodiment described above with respect to FIG. 14 c , in some examplesthe system 1400 may include an adapter 1404 having an annular groove1428, and a fitting 1402 having one or more protruding members 1434configured to at least partly engage (e.g., at least partly extend into,at least partly contact, at least partly slidably engage, etc.) thegroove 1428 when the fitting 1402 is releasably attached to the adapter1404. For example, similar to the adapter 1404 described with respect toFIG. 14 c , in example embodiments, the ring 1422 of the adapter 1404shown in FIG. 14 d may include a groove 1428 extending at least partly(and, in some examples, completely) around (e.g., concentrically) thelongitudinal axis X, and being shaped, sized, located, and/or otherwiseconfigured to accept the member 1434 and/or other structural feature ofthe adapter 1402. In such embodiments, the member 1434 and/or othercomponents of the fitting 1402 shown in FIG. 14 d may be substantiallysimilar to and/or the same as the corresponding components of thefitting 1402 described above with respect to FIG. 14 c , and the groove1428 and/or other components of the adapter 1404 may be substantiallysimilar to and/or the same as the corresponding components of theadapter 1404 described above with respect to FIG. 14 c.

In some embodiments, as shown in FIG. 14 d , in addition to the groove1428, the ring 1422 of the adapter 1404 may also include one or moresurfaces, sections, and/or other modified portions 1480 configured toaccept and/or otherwise engage with a corresponding additional member ofthe fitting 1402. In the example shown in the partial cross-section ofFIG. 14 d , the fitting 1402 may include a first arm 1408 a (not shown)and a second arm 1408 b opposite the first arm 1408 a. In such examples,a shelf 1410 a (not shown) and/or other radially inwardly facing surfaceor portion of the first arm 1408 a may form a first additional member1482 a (not shown) of the fitting 1402, and a shelf 1410 b and/or otherradially inwardly facing surface or portion of the second arm 1408 b mayform a second additional member 1482 b of the fitting 1402. As shown inFIG. 14 d , in such examples the modified portion 1480 of the ring 1422may be formed by and/or may comprise a surface and/or other portion ofthe ring 1422 disposed opposite the top surface 1426 and/or disposed ona radially outwardly facing portion of the ring 1422. In particular, insuch examples, the modified portion 1480 may at least partly face thetop surface of the cuff 12.

In some examples, the modified portion 1480 of the ring 1422 shown inFIG. 14 d may comprise an additional groove, channel, notch,indentation, hole, or other portion of the ring 1422 that, relative tothe ring 722 and/or the substantially planar bottom surface or ridge 724shown in FIG. 7 a , has been omitted (e.g., via a molding process) orremoved (e.g., via a mechanical or other removal process) from the ring1422. In such examples, the additional groove, channel, notch,indentation, hole, or other modified portion 1480 of the ring 1422 shownin FIG. 14 d may be substantially annular, may extend (at leastpartially) circumferentially around the longitudinal axis X, and/or mayotherwise be configured similar to the groove 1428 to facilitaterotation of the fitting 1402 relative to the adapter 1404.

As shown in FIG. 14 d , in some examples the modified portion 1480 ofthe ring 1422 may comprise a substantially planar surface and/or otherportion of the ring 1422 extending distally and radially inwardlybetween and/or from the top surface 1426 to the ridge 1424.Alternatively, in other embodiments the modified portion 1480 of thering 1422 may comprise a substantially curved, substantially concave,and/or substantially convex surface or portion of the ring 1422.

In any of the examples described herein, the groove 1428 may include aradially innermost sidewall that is radially spaced from a radiallyinnermost end (e.g., the radially innermost end 1430 described abovewith respect to FIG. 14 c ) of the top surface 1426) by a portion 1488of the top surface 1426. In such examples, the substantially planarsurface, curved surface, and/or other surface of the modified portion1480 may include a first end 1484 (e.g., a radially outermost end)disposed proximate, adjacent, and/or at a radially outermost end of thetop surface 1426. Further, in such examples the substantially planarsurface, curved surface, and/or other surface of the modified portion1480 may include a second end 1486 (e.g., a radially innermost end)disposed proximate, adjacent, and/or at a radially outermost end of theridge 1424. In such examples, the first end 1484 of the modified portion1480 may be radially spaced from a radially outermost sidewall of thegroove 1428 by an additional portion 1490 of the top surface 1426.

Additionally, in any of the examples described herein the shape, size,location, orientation, and/or other configuration of the modifiedportion 1480 may match a configuration of the first and secondadditional members 1482 a, 1482 b of the fitting 1402. For instance, thefirst and second additional members 1482 a, 1482 b may comprisesubstantially planar surfaces of the respective arms 1408 a, 1408 b.Alternatively, in other embodiments the first and second additionalmembers 1482 a, 1482 b may comprise substantially curved, substantiallyconcave, and/or substantially convex surfaces or portions of therespective arms 1408 a, 1408 b. In such examples, the first and secondadditional members 1482 a, 1482 b may mate with and/or otherwise atleast partially engage the first and second additional members 1482 a,1482 b when the fitting 1402 is removably attached to the adapter 1404.Such engagement may assist in minimizing and/or substantiallyeliminating lateral movement of the fitting 1402 relative to the adapter1404 when the fitting 1402 is removably attached to the adapter 1404.Such engagement may also provide additional rigidity, support, and/orstability to the removable connection between the fitting 1402 and theadapter 1404, while still facilitating rotation of the fitting 1402relative to the adapter 1404. Such engagement may also cause thelongitudinal axis Z of the fitting 1402 (FIG. 2 ) to be collinear withthe longitudinal axis X of the adapter 1404.

Further, the first and second additional members 1482 a, 1482 b and themodified portion 1474 may be disposed at complimentary angles relativeto, for example, the longitudinal axis X when the fitting 1402 isremovably attached to the adapter 1404. For instance, the portion of thering 1422 forming the modified portion 1480 may be disposed at an acuteincluded angle Θ relative to the longitudinal axis X. In such examples,the portions of the respective arms 1408 a, 1408 b forming the first andsecond additional members 1482 a, 1482 b may be disposed at respectivecomplimentary acute included angles A relative to the longitudinal axisX and an axis 1476 extending perpendicular to the longitudinal axis X.

Further, it is understood that in some embodiments at least one of thefirst and second additional members 1482 a, 1482 b may include and/orcomprise one or more pins, flanges, detents, and/or other extensions,and in such embodiments the portion of the ring 1422 forming themodified portion 1480 may include one or more grooves, channels,dimples, indents, and/or other structures configured to accept suchextensions.

Moreover, with reference to at least FIG. 14 f , in some examples thesystem 1400 may include an adapter 1404 having an annular groove 1428,and a fitting 1402 having one or more protruding members 1434 configuredto at least partly engage (e.g., at least partly extend into, at leastpartly contact, at least partly slidably engage, etc.) the groove 1428when the fitting 1402 is releasably attached to the adapter 1404. Forexample, similar to the adapter 1404 described with respect to FIGS. 7a-7 g , in example embodiments, the ring 1422 of the adapter 1404 mayinclude a groove 1428 extending at least partly (and, in some examples,completely) around (e.g., concentrically) the longitudinal axis X, andbeing shaped, sized, located, and/or otherwise configured to accept themember 1434 and/or other structural feature of the adapter 1402. Asshown in at least FIG. 14 f , such a member 1434 may extend distally(e.g., in a direction toward the cuff 12 when the fitting 1402 isremovably attached to the adapter 1404) from an outer surface 1436 ofthe fitting 1402 disposed opposite and/or facing the top surface 1426when the fitting 1402 is removably attached to the adapter 1404. Asdescribed above with respect to FIG. 14 a , in some examples, the member1434 may comprise a shaft, pin, rod, tab, rib, ring, ridge, flange,and/or other extension of the body 1406 protruding from the outersurface 1436, and the engagement between the member 1434 and the groove1428 may assist in laterally and/or otherwise aligning the fitting 1402with the adapter 1404 when removably attaching the fitting 1402 to theadapter 1404. Example members 1434 of the present disclosure may haveany shape, size, cross-sectional profile and/or other configuration tofacilitate such functionality.

In such examples,the member 1434 may include a radially outermost sidewall 1466 and aradially innermost sidewall 1468, and the radially outermost sidewall1466 may extend at an acute included angle relative to the radiallyinnermost sidewall 1468. Moreover, the configuration of the groove 1428shown in FIG. 14 f may substantially match and/or otherwise correspondto the shape, size, cross-sectional profile, location, and/or otherconfiguration of the member 1434. For example, the groove 1428 mayinclude a radially innermost sidewall 1454, and a radially outermostsidewall 1456, and the radially innermost sidewall 1454 may extend at anacute included angle relative to the radially outermost sidewall 1456.In such examples, the radially innermost sidewall 1454 of the groove1428 may extend substantially parallel to the radially innermostsidewall 1468 of the member 1434 when the fitting 1402 is removablyattached to the adapter 1404.
